Cyano-substituted norbornene polymers blended with polyvinyl chloride resins |
摘要 |
A resin composition is prepared from 5 to 95 parts by weight of a polymer prepared by ring-opening polymerization of cyano-substituted norbornene derivatives having at least one nitrile group or substituents including nitrile group and 95 to 5 parts by weight of (a) homopolymer or copolymer of vinyl chloride, (b) styrene homopolymer or vinyl copolymer containing at least 50 per cent by weight of at least one vinyl compound selected from the group consisting of styrene, acrylonitrile and methyl methacrylate, (c) said homopolymer or copolymer compounded with elastomer, or (d) graft copolymer obtained by grafting at least one of said vinyl compounds to said elastomer.
