ABSTRACT:
A composition contains (A) 60 to 80 parts by weight of vinyl chloride polymer (B) 11 to 23 parts by weight of an acrylic elastomeric polymer formed from butyl acrylate and methyl methacrylate and (C) 15 to 30 parts by weight of a second acrylic polymer formed from methyl methacrylate.
The composition is useful for moldings and extrusions particularly where good weatherability and/or reduced smoke generation are required and can be directly bonded to and reinforced with polyester.
