Processing aid, vinyl chloride resin composition containing the same, and process for producing molded article with the same |
摘要 |
The present invention provides a processing aid that reduces ungelled products and flow marks generated on a sheet, and improves releasability of the sheet from the metallic surface of a roll, with the processing aid comprising:a copolymer (A) obtained by copolymerizing a monomer mixture comprising 70 to 90% by weight of methyl methacrylate, 10 to 30% by weight of acrylate or methacrylate other than methyl methacryrate and a different type of monomer capable of being copolymerized with those monomers; anda copolymer (B) obtained by copolymerizing a monomer mixture comprising at least 30% by weight of methyl methacrylate and a monomer having as constitutional units at least one type selected from methacrylates other than methyl methacrylate, acrylates, aromatic alkenyl compounds and other monomers.
