摘要
Vinyl chloride polymer (PVC) composition especially suitable for calendering which comprises PVC, at least one copolymer of an alkyl (meth)acrylate (preferably n-butyl acrylate) and alpha methyl styrene of low molecular weight (10,000 to 100,000) achieved by performing the copolymerization in the presence of a chain transfer agent, particularly cyclohexene, and which composition optionally contains a processing aid, and wherein the PVC and said at least one alkyl (meth)acrylate copolymer are admixed by performing the VC polymerization process to produce the PVC in the presence of the alkyl (meth)acrylate copolymer.
