TLDR
Improved molding compositions based on polyvinyl halides modified with acrylic polymers are provided in this article, where polymeric modifiers have molecular weights of from 1,500 to less than 10,000 and contain residues of (A) from 75 to 100 percent by weight alkyl methacrylate and (B) from 0 to 25 percent of at least one additional ester of acrylic or methacrylic acid, styrene or substituted styrene.Abstract:
Improved molding compositions based on polyvinyl halides modified with acrylic polymers are provided. The polymeric modifiers have molecular weights of from 1,500 to less than 10,000 and contain residues of (A) from 75 to 100 percent by weight alkyl methacrylate and (B) from 0 to 25 percent of at least one additional ester of acrylic or methacrylic acid, styrene or substituted styrene. The molding compositions provide improved flow characteristics and processing characteristics.read more
