Title:
HEAT-RESISTANT, FLAME-RETARDANT AND IMPACT-RESISTANT RESIN COMPOSITION
Document Type and Number:
Japanese Patent JPS60208345
Kind Code:
A
Abstract:

PURPOSE: To produce a composition having excellent heat-resistance, flame- retardance and impact resistance, by compounding an α-methylstyrene/acrylonitrile copolymer with a rubber such as MBS resin and a chlorine-containing resin.

CONSTITUTION: The objective composition can be produced by compounding (A) a copolymer obtained by the suspension or bulk polymerization of 30W80pts.(wt.) of α-methylstyrene, 15W50pts. of acrylonitrile and 0W50pts. of other monomer copolymerizable therewith, (B) a rubber selected from chlorinated polyethylene, MBS resin, acrylic rubber resin, styrene-butadiene resin and NBR resin, and (C) a chlorine-containing resin. The polymerization initiator of the component A is a polyfunctional organic peroxide and/or an azo compound. The component C is e.g. ethylene-vinyl chloride copolymer, aryl chloride-vinyl chloride copolymer, etc. having an average polymerization degree of 400W800.
