FLAMEPROOF THERMOPLASTIC RESIN COMPOSITION WITH ENVIRONMENTAL AFFINITY

摘要

PURPOSE: Provided is flame-proof thermoplastic resin composition using cyclic alkyl phosphonic compound as the flame retardant agent to obtain environmental affinity without halogen compound inducing environmental pollution. CONSTITUTION: The flame-proof composition comprises (A) 100 parts by weight of transparent ABS resin including (A1) 20-100 wt.% of graft copolymer resin consisting of 5-60 parts by weight of rubber polymer, 1-30 parts by weight of aromatic vinyl compound, 10-40 parts by weight of unsaturated nitrile compound and 10-60 parts by weight of alkyl methacrylate; and (A2) 0-80 wt.% of styrene copolymer resin consisting of 40-80 parts by weight of alkyl methacrylate compound, 10-30 parts by weight of aromatic vinyl compound and 0-50 parts by weight of unsaturated nitrile compound, and (B) 0.1-15 parts by weight of cyclic alkyl phosphonic compound.
