Description
本発明は、不飽和カルボン酸、その無水物または誘導体がグラフト共重合した変性ポリプロピレン樹脂およびその製造方法に関するものである。更に詳しくは、不飽和カルボン酸、その無水物または誘導体の含有量と分子量とのバランスおよび他の素材との親和性に優れ、かつ製造コストが安価である変性ポリプロピレン樹脂およびその製造方法に関する。 The present invention relates to a modified polypropylene resin obtained by graft copolymerization of an unsaturated carboxylic acid, an anhydride or a derivative thereof, and a method for producing the same. More specifically, the present invention relates to a modified polypropylene resin having an excellent balance between the content and molecular weight of an unsaturated carboxylic acid, its anhydride or derivative, and affinity with other materials, and a low production cost, and a method for producing the same.
ポリプロピレン樹脂は低密度で機械物性、耐薬品性等に優れ、かつ成形加工が容易であることから、自動車部品、家電部品、各種容器、シート、フィルム、繊維等の幅広い分野で使用されている。また性能を向上させる手段として、他の素材との複合が行われ、例えば無機充填剤との組み合せによる剛性および耐熱性に優れた複合材、あるいは他の樹脂フィルムとの組み合せによる複合フィルムなど多くのものが知られている。 Polypropylene resin is used in a wide range of fields such as automobile parts, home appliance parts, various containers, sheets, films, and fibers because it has a low density, excellent mechanical properties, chemical resistance, and the like, and can be easily molded. In addition, as a means to improve performance, it is combined with other materials, for example, a composite material excellent in rigidity and heat resistance in combination with an inorganic filler, or a composite film in combination with another resin film. Things are known.
しかしながら、ポリプロピレン樹脂は炭化水素を主体とする骨格であり、その分子鎖中に極性基を含有していないため、他の素材に対する相溶性が乏しく、このためそのままでは塗料や接着剤の直接塗布、あるいは金属との接着または極性樹脂との複合化などが困難であるので、ポリプロピレン樹脂の改質が行われている。 However, polypropylene resin is a skeleton mainly composed of hydrocarbons, and since it does not contain polar groups in its molecular chain, it has poor compatibility with other materials. Alternatively, since it is difficult to bond with a metal or to combine with a polar resin, the polypropylene resin is modified.
他の素材に対する相溶性を改質するため、ポリプロピレン樹脂に無水マレイン酸などの極性基を有するビニルモノマーまたはその誘導体をグラフトする方法が提案されている。しかし、一般的に、ポリプロピレン樹脂に不飽和カルボン酸またはその誘導体およびラジカル開始剤を作用させると、ポリプロピレン分子鎖中にラジカルが形成され、不飽和カルボン酸またはその誘導体のグラフト共重合が進行してグラフト変性物が得られるが、これと同時にポリプロピレン分子鎖切断による分子量低下が起こる。このため、グラフト変性物の分子量は変性前のポリプロピレン樹脂の分子量よりかなり小さくなる。分子量が大きく低下すると、ポリプロピレン樹脂が本来有している機械物性などが失われるので、ポリプロピレン分子鎖中に形成されたラジカルに、効率よく不飽和カルボン酸またはその誘導体を付加させる必要がある。 In order to modify the compatibility with other materials, a method of grafting a vinyl monomer having a polar group such as maleic anhydride or a derivative thereof onto a polypropylene resin has been proposed. However, generally, when an unsaturated carboxylic acid or its derivative and a radical initiator are allowed to act on a polypropylene resin, a radical is formed in the polypropylene molecular chain, and the graft copolymerization of the unsaturated carboxylic acid or its derivative proceeds. A graft modified product is obtained, but at the same time, the molecular weight is reduced due to polypropylene molecular chain scission. For this reason, the molecular weight of the graft modified product is considerably smaller than the molecular weight of the polypropylene resin before modification. When the molecular weight is greatly reduced, the mechanical properties inherent to the polypropylene resin are lost, so it is necessary to efficiently add an unsaturated carboxylic acid or a derivative thereof to a radical formed in the polypropylene molecular chain.
したがって、得られた変性ポリプロピレン樹脂の分子量が大きく、高グラフト量での変性ポリプロピレン樹脂を低コストで効率よく製造することができる方法は、工業的に非常に重要となる。 Therefore, a method capable of efficiently producing a modified polypropylene resin with a high molecular weight at a low cost is very important industrially because the obtained modified polypropylene resin has a large molecular weight.
ところで、特開昭４４−１５４２２号公報および特開昭５２−３０５４５号公報では、炭化水素系の溶媒中で結晶性ポリプロピレン樹脂を加熱溶解あるいは膨潤させた後、無水マレイン酸およびラジカル開始剤を作用させて変性ポリプロピレン樹脂を調製している。この製造方法によれば無水マレイン酸を効率的にグラフトすることができ、未グラフトの無水マレイン酸含有量の少ない変性ポリプロピレン樹脂が得られる。しかしながら、製造工程が煩雑であるため工業的に有効な方法とはいえない。 In JP-A-44-15422 and JP-A-52-30545, a crystalline polypropylene resin is heated and dissolved or swollen in a hydrocarbon solvent, and then maleic anhydride and a radical initiator are used. Thus, a modified polypropylene resin is prepared. According to this production method, maleic anhydride can be efficiently grafted, and an ungrafted modified polypropylene resin having a low content of maleic anhydride can be obtained. However, it is not an industrially effective method because the manufacturing process is complicated.
また特開平６−３１３０７８号公報では、押出機中で高濃度の無水マレイン酸をグラフトした変性ポリプロピレン樹脂により、ナイロンとの相溶性を改良している。しかしながら、この変性ポリプロピレン樹脂は分子量が非常に小さいため機械物性の改良効果は期待できない。さらに変性ポリプロピレン樹脂中に未グラフトの無水マレイン酸が残存するため、他の素材との接着性に悪影響を及ぼす可能性がある。 In JP-A-6-313078, compatibility with nylon is improved by a modified polypropylene resin grafted with a high concentration of maleic anhydride in an extruder. However, since this modified polypropylene resin has a very small molecular weight, it cannot be expected to improve the mechanical properties. Furthermore, ungrafted maleic anhydride remains in the modified polypropylene resin, which may adversely affect the adhesion to other materials.

Any compound can be used without limitation. When the polypropylene resin is modified with the component (B) alone, for example, maleic anhydride alone, a chain transfer reaction of the maleic anhydride radical generated at the time of modification to the polypropylene resin occurs. A decrease occurs and a large amount of ungrafted maleic anhydride is generated. The unsaturated bond-containing radical reactive monomer (C) used in the present invention is blended in order to suppress such a chain transfer reaction of maleic anhydride.

When any (meth) acrylic acid ester is used, the effect of suppressing the molecular weight reduction of the modified polypropylene resin is recognized, but the effect depends on the blending amount. Therefore, when the number of carbons in the ester part is large (specifically, the number of carbons in the ester part is 8 or more), that is, when the molecular weight of the (meth) acrylic acid ester is large, The blending amount increases. When melt-modifying using a nonpolar resin such as polypropylene resin, the addition of a large amount of such polar liquid components deteriorates the properties of the mixture and causes problems such as bridging under the hopper of the extruder during production. Occurs and causes production problems. Therefore, in order to reduce the addition amount as much as possible, the (C) component is preferably a (meth) acrylic acid ester having an ester moiety having 7 or less carbon atoms.

The difference between the melting point (Tm (PP)) of the polypropylene resin used for modification and the melting point (Tm (MPP)) of the modified polypropylene resin is usually in the range of 0 to 15 ° C, preferably 0 to 10 ° C. desirable. In general, when a radical initiator is allowed to act on a polypropylene resin to graft polymerize a radical reactive monomer having an unsaturated bond, the molecular weight and melting point of the polypropylene resin are lowered due to radical generation simultaneously with the grafting of the monomer. At this time, how efficiently the generated polymer radicals and / or monomer radicals are added, that is, how to obtain a modified polypropylene resin having the same amount of grafted monomers (graft amount), higher molecular weight, and high melting point. Is an issue. If the molecular weight is excessively decreased and / or the melting point is excessively decreased even if a predetermined graft amount can be obtained, the intrinsic viscosity [η] is less than 0.7 dl / g, and / or When the difference between the melting point of the used polypropylene resin and the melting point of the modified polypropylene resin is 15 ° C. or more, the mechanical properties inherent to the polypropylene resin are not exhibited.
また、本発明の変性ポリプロピレン樹脂において、不飽和カルボン酸および／またはその誘導体（Ｂ）のグラフト量をＭＧ（重量％）とした場合、ＭＧは、０．８≦ＭＧ≦５、好ましくは１≦ＭＧ≦５である。ＭＧが１未満であれば、グラフト量が少ないため、所定の密着や接着性能が得られない。ＭＧが５を超えるとポリプロピレン樹脂との相溶性が低下し、逆に密着や接着性能が低下してしまう。 In the modified polypropylene resin of the present invention, when the graft amount of the unsaturated carboxylic acid and / or derivative (B) is MG (% by weight), MG is 0.8 ≦ MG ≦ 5, preferably 1 ≦ MG ≦ 5. If MG is less than 1, the amount of grafting is small, so that predetermined adhesion and adhesion performance cannot be obtained. When MG exceeds 5, compatibility with a polypropylene resin is lowered, and conversely, adhesion and adhesion performance are lowered.
更に、本発明の変性ポリプロピレン樹脂においては、不飽和カルボン酸および／またはその誘導体（Ｂ）のグラフト量をＭＧ（重量％）、（Ｂ）成分と異なる不飽和結合含有するラジカル反応性モノマー（Ｃ）のグラフト量をＥＧ（重量％）とした場合に、ＥＧ／ＭＧは０＜（ＥＧ／ＭＧ）≦１、好ましくは０．１≦（ＥＧ／ＭＧ）≦０．７５である。（ＥＧ／ＭＧ）＞１の場合、つまりＥＧがＭＧよりも多くなると、ポリプロピレン樹脂との相溶性が低下し、逆に密着や接着性能が低下してしまうため、好ましくない。 Furthermore, in the modified polypropylene resin of the present invention, the radical reactive monomer (C) containing an unsaturated bond different from the component (B) in which the graft amount of the unsaturated carboxylic acid and / or its derivative (B) is MG (wt%). ) Is defined as EG (% by weight), EG / MG satisfies 0 <(EG / MG) ≦ 1, preferably 0.1 ≦ (EG / MG) ≦ 0.75. In the case of (EG / MG)> 1, that is, when EG is larger than MG, compatibility with polypropylene resin is lowered, and conversely, adhesion and adhesion performance are lowered, which is not preferable.
本発明の変性ポリプロピレン樹脂は、上記関係式（i）、（ii）、（iii）、及び（iv）を満足するため、ポリプロピレン本来の特性を保持しつつ、従来からのポリプロピレン樹脂の欠点であった塗料や接着剤との密着性を改善し、かつ極性樹脂との複合化においても相溶性を改善したポリプロピレン樹脂組成物を得ることができる。更にこの変性ポリプロピレン樹脂は単独でも使用できるし、改質材としても使用できる。 The modified polypropylene resin of the present invention satisfies the above-mentioned relational expressions (i), (ii), (iii), and (iv), and thus is a drawback of conventional polypropylene resins while maintaining the original properties of polypropylene. Thus, a polypropylene resin composition having improved compatibility with paints and adhesives, and improved compatibility even in combination with a polar resin can be obtained. Furthermore, this modified polypropylene resin can be used alone or as a modifier.

The temperature at which the kneader is kneaded (for example, the cylinder temperature for an extruder) is 100 to 300 ° C, preferably 160 to 250 ° C. If the temperature is too low, the graft amount may not be improved, and if the temperature is too high, decomposition of the resin may occur. In order to remove ungrafted components, it is preferable to use a kneader equipped with a vacuum vent device.
