FOAMABLE POLY(VINYL CHLORIDE) RESIN COMPOSITION |
摘要 |
Foamable vinyl chloride-base resin compositions whereby foaming ratio can be largely elevated. Compositions comprising 0.5 to 30 parts by weight of a (meth)acrylate-base copolymer, which is a polymer mixture obtained by, in th e presence of a (co)polymer latex obtained by emulsion-polymerizing 100 parts by weight of a vinyl chloride resin with 50 to 100 parts by weight of a monomer mixture (a) comprising 50 to 100 parts by weight of methyl methacrylate and 0 to 50% by weight of a monomer selected from among methacrylates excluding methyl methacrylate and acrylates, adding 0 to 50 parts by weight of a monom er mixture (b) comprising 0 to 50% by weight of methyl methacrylate and 50 to 100% by weight of at least one monomer selected from among methacrylates excluding methyl methacrylate and acrylates is added to give a total amount of 100 parts by weight followed by polymerization; 0.5 to 15 parts by weight of water; and 0 to 20 parts by weight of a pyrolytic foaming agent.
