Title:
THERMOPLASTIC RESIN COMPOSITION
Document Type and Number:
Japanese Patent JPH0291143
Kind Code:
A
Abstract:
PURPOSE:To improve heat resistance, weatherability, impact resistance, processing (molding) stability and mechanical strengths by compounding a mixture of a chlorinated polymer and an alpha-methylstyrene-acrylonitrile copolymer with a specified polymer mixture. CONSTITUTION:A mixture (A) is obtd. by mixing 80-40 pts.wt. (hereinbelow merely pts.) chlorinated polymer which is a mixture of a vinyl chloride polymer and, if necessary, a chlorinated vinyl chloride polymer with 20-60 pts. alpha- methylstyrene-acrylonitrile copolymer. Another mixture (B) is obtd. by mixing 80-20wt.% (hereinbelow merely %) graft polymer obtd. by grafting vinyl chloride and, if necessary, a mixture of another monomer therewith onto 30-80% ethylene-vinyl acetate copolymer consisting of 80-20% ethylene and 20-80% vinyl acetate with 20-80% impact resistance-reinforcing agent obtd. by emulsion polymn. (e.g., a modified methyl methacrylate-butadiene-styrene resin contg. an acrylate component and an acrylonitrile component). 100 pts. component A is compounded with 8-20 pts. component B.
