FLAME RETARDANT INJECTION-MOLDING RESIN COMPOSITION |
摘要 |
A flame-retardant injection-molding resin composition. The composition contains (A) 100 parts by weight of a flame-retardant resin composed of 30% to 80% by weight of styrene resin having a reduced viscosity of methyl-ethyl-ketone soluble portions of 0.2 to 0.55 dl/g in N,N-dimethylformamide at a concentration of 0.3 g/dl at 30.degree.C, and from 20% to 70% by weight of a polyvinyl chloride resin having a polymerization degree of from 400 to 800; and (B) 0.5 to 10 parts by weight of a copolymer of from 30% to 35% by weight of a vinyl cyanide compound, 30% to 97% by weight of an alkyl acrylate and o% to 67% by weight of a vinyl monomer being copolymerizable with the vinyl cyanide compound and the alkyl acrylate. The flame-retardant injection-molding resin composition provides injection-molded articles of high impact strength and low delamination tendency and has excellent thermal stability, flame resistance and heat stability.
