Patent ID: 7923508

Claim:
A flame retardant styrene-based resin composition with high impact property comprising: 100 parts by weight of a rubber-modified styrene-based copolymer base resin; 1-30 parts by weight of a flame retardant; 0.5-15 parts by weight of a flame retardant aid; and 0.1-15 parts by weight of a styrene-containing graft copolymer, wherein the rubber-modified styrene-based copolymer base resin consists essentially of a matrix of polystyrene and a rubber polymer particle dispersed in the matrix of polystyrene; and the styrene-containing graft copolymer is a styrene-conjugated diene graft copolymer in which only styrene is grafted to 50 to 90% by weight of a conjugated diene rubber having an average particle diameter of 500-4000 Å, based on the total weight of styrene-conjugated diene graft copolymer.
