The extruded mold is extruded, and the extruded molten monofilament is cut to obtain pellets. On the other hand, when a powdered acrylic multilayer structure polymer is used in this method, dust may be scattered when mixed with a methacrylic resin, and workability may be poor. In addition, the use of a particulate acrylic multilayer structure polymer has improved problems such as dust scattering when using a powder, but it cannot be sufficiently improved. Therefore, it is preferable that the acrylic multilayer structure polymer has a pellet shape having excellent processing properties.

In order to meet this requirement, it is necessary to provide an acrylic multilayer structure polymer or a main pellet having a large rubber-like strength. In addition, the conventional powdery or granular acrylic multilayer structure polymer and methacrylic resin are mixed, and the conventional extruder is used for the capture.

In other words, in the example of the previous document, the specific description of the pellets (or main pellets) of the multi-layer acrylic polymer containing acrylic fluorene has a rubber-like elastomer content of 3GX (Yamoto Tokai Sho 6 2-2 3 0 No. 8 No. 1) or 17.5% (Japanese Laid-open Patent Publication No. 5-1 7 6 54) has less rubber content, and there is no rubber-like elastomer with a content of 50 X or more. The manufacturing technology of rubber-containing pellets is a graft polymer formed by aggregating ABS resin, which is one of the impact-resistant resins, by emulsifying ethylene monomer in a diene strip rubbery polymer and graft polymerization. The polymer slurry obtained from the latex coagulation is directly supplied to the squeeze water extruder. Once the water is extruded, kneaded, melted, and plasticized in the barrel, the strands are continuously extruded from the nozzle at the front of the extruder. A method of cutting the material to produce a pellet-shaped ABS resin is known, and the polymer slurry is mixed with a vinyl polymer polymer slurry obtained by suspension or block polymerization. A method for producing a pelletized ABS resin in the same manner as described above for a dewatering extruder is also known (Japanese Patent Publication No. 59-37021). Β, once, the melting of the ABS resin and the methacrylic resin The properties are significantly different, so the squeeze dewatering extruder technology is suitable for soft polymers that are easier to melt, such as ABS resins, but hard polymers, such as acrylic polymer, are not as good. In other words, in order to not impair the original gloss and transparency of the methacrylic strip resin and to impart impact resistance, the paper size must comply with the China National Standard Car (CNS) A4 specification (210X297). ----.------ Install ------------ Order ------- (Please read the precautions on the back before filling in this page) 4 4 i 94¾ head A7 B7 V. Invention Explanation (4)-Make the content of rubber-like components such as alkyl acrylate in the acrylic multi-layered multilayer structure polymer small, and the proportion of hard components such as alkyl methacrylate more. When the ratio of rubber-like components is large, the tortuosity changes greatly with respect to temperature, and the optical characteristics are impaired. In addition, the acrylic multilayer structure polymer must be a hard material, and it is difficult for the polymer particles in the emulsion latex to cause melting during solidification, and the moisture content of the recovered wet-like polymer tends to be higher. For practical applications of impact-resistant acrylic resins, impact-resistant acrylic resins have good molding appearance and can be widely used in kanban or front panels of vending machines, automotive wipers, etc. Demand for performance is getting higher and higher. Therefore, in general, when a composition is produced by mixing a polyacrylic acid multi-layer structure polymer and a methacrylic resin M, an organic stabilizer is added to further enhance the method of improving exogenous or weatherability. If there are many types of stabilizers used in this method, a large amount of labor will be required and production efficiency will be reduced, resulting in increased product costs. In addition, depending on circumstances such as environmental pollution at the time of addition of the stabilizer, the resulting acrylic linden tree i target composition may be contaminated and its performance may be reduced.

The ratio of the alkyl acrylate to the monofunctional monomer is determined by the tortuosity depending on the transparency requirements of the resin. However, if the alkyl acrylate is small, it is easy to reduce the impact resistance. The lower the Tg of the polymer constituting the (α) rubber-like elastomer, the higher the impact resistance of the obtained resin composition at low temperature. Therefore, the Tg when the M is polymerized alone is preferably 2 5 10 M, and more preferably 1 or less. Examples of the alkyl acrylate having an alkyl group having a carbon number of 8 M include methyl acrylate, ethyl acrylate, propylene acrylate, n-butyl acrylate, and 2-ethylhexyl acrylate, and n-butyl acrylate is particularly preferred. These can be used alone or in combination. Examples of copolymerizable monofunctional monomers include aromatic unsaturated monomers such as styrene, vinyltoluene, and sigma-methylstyrene; methacrylic monomers such as methacrylic acid benzene and naphthyl methacrylate. Alas. Especially, the monomer M styrene for adjusting the tortuosity is preferable. Graft crossover agents are compounds with several pseudo-functional groups. The reactivity of at least one functional group is different from the reactivity of other functional groups, such as acrylic, methacrylic, maleic, or allyl fumarate. Stuffed and so on. Of these, allyl acrylate and allyl methacrylate are particularly preferred.

Description of the invention (15) 'It is better to slowly flow into the coagulant solution to solidify. If the wire speed is too fast, the moisture content of the coagulated powder is not desirable. The coagulated powder (wet polymer) obtained by coagulating the emulsified latex was washed with sufficient water in K to 5 to 100 times the weight of the polymer. When the water used for washing is the least, the amount of residual coagulation is large, and the appearance or physical properties of the pellets may be damaged. After the coagulated powder is washed with water, it is dewatered by a M centrifugal dehydrator and the like, and is supplied to the press dewatering extruder as (X) water-containing polymer. In the present invention, the (X) water-containing polymer obtained by solidifying, washing and dehydrating the emulsion latex of the multilayer polymer is dried by using a dewatering extruder. At this time, (i) organic stabilizers such as (ii) phosphorus-based compounds, hindered phenol hydrazone compounds, and hindered amine-based compounds may be added as needed. Generally, the lower the water content of the solidified powder in the dry refining process, the faster the drying speed can be effectively achieved. The problematic water will be in the microvoids formed by the multi-layer polymer in the size of several microns. Therefore, after the solidified powder is dried, the mercury volume measured by the mercury intrusion method and the pore volume at a pore diameter of 5 // mK is equivalent to the dry unit of 0.7 ml K, which has a small water content and has excellent drying efficiency. The smaller the void volume is desired. The void volume is very large. Because there is a relatively large amount of water in the solidified powder, the drying speed is slower. Since the solidified powder is effectively dried by using a squeeze dewatering extruder, the average particle size of the solidified powder can be effectively increased, and the amount of fine powder can be reduced. Specifically, the coagulated powder has the above-mentioned void structure, and the fine powder ratio at a particle diameter of the coagulated powder of 212 M is 40 weight S: the following is preferred. The smaller the proportion of fine powder, the better. If the proportion of fine powder in the coagulation powder is more, it will increase the supply of coagulation powder. 15-This paper size is applicable to China® House Standard Rate (CNS) M Regulation (2!
