Vinyl chloride resin composition. |
摘要 |
<p>A composition comprising polyvinyl chloride and a novel polymer processing aid is provided. The polymer processing aid can be obtained either by blending in latex form an alkyl methacrylate copolymer (A) and a copolymer (B) comprising as its essential constituents an alkyl methacrylate, a dialkyl itaconate or an alkyl acrylate, and a diolefin, or by copolymerizing one of the copolymers in the presence of the other copolymer.</p><p>The polymer processing aid thus obtained improves the processability of the vinyl chloride resin composition with less reduction in impact strength.</p> |
