本発明はフィルム或いはシート状成型物のための酢酸セ
ルロース組成物に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to cellulose acetate compositions for film or sheet moldings.
透明な有機高分子物質をフィルム状に成型したものは、
今日光学的用途に多用されている。A transparent organic polymer material molded into a film is
Today it is widely used in optical applications.
例えば、液晶表示装置の基盤に有機高分子フィルムを用
いると、無機杯料に比べて、装置の軽量化、薄型化、デ
ザインの自由さ、などの利点が得られる。特にこの用途
にはセルロース系フィルム、中でも酢酸セルロースは無
色透明性がよく、偏光性が小さいために利用されている
。ただし、酢酸セルロースは単独では成型加工性に乏し
いので、リン酸アルキルエステル、フタル酸アルキルエ
ステルなどの低分子可塑剤を２０〜３０重量％含有する
組成物として成型加工するのが普通である。For example, when an organic polymer film is used as the base of a liquid crystal display device, advantages such as lighter weight, thinner device, and freedom of design can be obtained compared to inorganic materials. In particular, cellulose-based films, especially cellulose acetate, are used for this purpose because they are colorless and transparent and have low polarization. However, since cellulose acetate alone has poor moldability, it is usually molded into a composition containing 20 to 30% by weight of a low-molecular plasticizer such as an alkyl phosphate or an alkyl phthalate.
しかしながら、このような低分子可塑剤を含有する酢酸
セルロースフィルムを液晶表示装置の基盤として用いる
と基盤と接触している液晶物質中へ可塑剤が溶出移行し
、液晶の配向性が乱れる原因となる。また、基盤に電導
性膜が接着されている場合には、やはり電導性膜中へ可
塑剤が移行し、その電気的特性を低下さす傾向がある。However, when a cellulose acetate film containing such a low-molecular plasticizer is used as a base for a liquid crystal display device, the plasticizer is eluted and migrated into the liquid crystal material that is in contact with the base, causing disorder in the alignment of the liquid crystal. . Furthermore, when an electrically conductive film is adhered to the substrate, the plasticizer tends to migrate into the electrically conductive film and deteriorate its electrical properties.
本発明者等は、このような低分子可塑剤を含有しないで

好なフィルムを得る組成物であることを認め、本発明に
到達した。The present inventors have attempted to obtain a film with excellent moldability and shape stability without containing such low-molecular plasticizers.
As a result of research on cellulose acetate compositions that can be used for cellulose acetate, it was found that a composition that has a high degree of esterification of cellulose with an organic acid that is miscible with cellulose acetate can produce a good film without a low-molecular plasticizer. , arrived at the present invention.
本発明に使用する酢酸セルロースは酢化度（酢酸含量）
５５〜６０チの範囲にある所謂三酢酸セルロース（エス
テル化度２．４〜２．８）が適当であるが、目的によっ

ルロースには、重合度２００以上のプラスチックス或い
は繊維用グレードを使用することができる。The degree of acetylation (acetic acid content) of cellulose acetate used in the present invention
So-called cellulose triacetate (esterification degree 2.4-2.8) having an acetylation degree of 55 to 60 degrees is suitable, but depending on the purpose, so-called cellulose diacetate (esterification & 2.8 degrees) having an acetylation degree of 48 to 52 degrees is suitable. 0 to 2.2) 4 can be used. For these cellulose acetates, plastic or fiber grades having a degree of polymerization of 200 or more can be used.
酢酸セルロースと混和性のあるセルロース有機酸エステ
ルとしては、例えば酢酸プロピオン酸セルロース、酢酸
酪酸セルロースなどが適当であり、それらの分子量は主
成分である酢酸セルロースの半分以下であることが望ま
しい。Suitable cellulose organic acid esters that are miscible with cellulose acetate include, for example, cellulose acetate propionate and cellulose acetate butyrate, and it is desirable that their molecular weight is less than half that of cellulose acetate, which is the main component.
上記のセルロースエステルの市販の塗料グレードのもの
を用いると、それらの条件を満足させることができる。These conditions can be satisfied by using commercially available paint grade cellulose esters mentioned above.
また同じ酢酸セルロースであっても、酢化度の低いもの
、例えばエステル化度が２０以下のものは本用途に使用
することができる。Further, even if the cellulose acetate is the same, one with a low degree of acetylation, for example, one with a degree of esterification of 20 or less, can be used for this purpose.
このような重合度の低いセルロースエステルを重合度２
００以上の酢酸セルロースと混合したものが本発明の組
成物であるが、組成物中の低分子セルロースエステルの
量を２〜１０重量％としたとき、成型加工性にすぐれた
組成物が得られる。This type of cellulose ester with a low degree of polymerization has a degree of polymerization of 2.
The composition of the present invention is one that is mixed with cellulose acetate of 0.00 or more, but when the amount of low molecular weight cellulose ester in the composition is 2 to 10% by weight, a composition with excellent moldability can be obtained. .
成型加工法としては、例えば共通溶剤に溶解し、溶液を
キャスティングしてフィルムとすることができる。As a molding method, for example, it can be dissolved in a common solvent and the solution can be cast to form a film.
低分子セルロースエステルヲ酢酸セルロースに対して配
合すると、一般にフィルムの伸度の大きなものが得られ
る。When a low-molecular cellulose ester is blended with cellulose acetate, a film with high elongation is generally obtained.
フィルムの加工性は強度及び伸度に依存するが酢酸セル
ロースフィル・ムは強度が１０００ｋｇ／Ｃｒｌ程度で
あり、この場合伸度が２０％以上ないとカッティング加
工性並びにカッティング端面の安定性が悪くなる。一般
に伸度は低分子セルロースエステル量の増大とともに大
きくなるが、低分子セルロースエステル量が１５チ以上
になると強度が低下する傾向がみられる。The processability of a film depends on its strength and elongation, but the strength of cellulose acetate film is about 1000 kg/Crl, and in this case, if the elongation is not 20% or more, cutting processability and stability of the cutting end face will deteriorate. . Generally, elongation increases as the amount of low-molecular cellulose ester increases, but when the amount of low-molecular cellulose ester exceeds 15 inches, the strength tends to decrease.
酢酸セルロースの他の特徴の一つに、熱融着性の小さい
ことがあげられる。低分子可塑剤を配合すると、この特
性は顕著に失われる。一方低分子セルロースエステルを
配合した組成物に於いてはこの特性は維持される。Another feature of cellulose acetate is that it has low thermal adhesiveness. This property is significantly lost when low-molecular plasticizers are incorporated. On the other hand, this property is maintained in a composition containing a low molecular weight cellulose ester.
即ち、本発明は酢酸セルロース９０〜９８重量−と該酢
酸セルロースよりも重合度が低いセルロースエステル２
〜１０重量％とからなり、低分子可塑剤を実質的に含有
しないことを特徴とする酢酸セルロース組成物に関する
ものである。That is, the present invention uses cellulose acetate 90 to 98% by weight and cellulose ester 2, which has a lower degree of polymerization than the cellulose acetate.
The present invention relates to a cellulose acetate composition characterized in that it consists of ~10% by weight and is substantially free of low-molecular plasticizers.
本発明の組成物は透明性にすぐれ、偏光性の少いことが
特徴であり、液晶表示装置の基盤以外にもこれらの特性
を利用するような成型物、例えば画像形成用トナー粒子
などの製造に用いることができる。The composition of the present invention is characterized by excellent transparency and low polarization, and can be used in the production of molded products that utilize these properties in addition to substrates for liquid crystal display devices, such as toner particles for image formation. It can be used for.
