摘要：
A flame-retardant styrene resin composition comprising 100 parts by weight of a styrene resin, 1 to 25 parts by weight of at least one flame retarder (A) represented by the formula (I):
wherein X is Br or Cl; and each of h and i is an integer of 2 to 5, and 1 to 25 parts by weight of at least one flame retarder (B) represented by the formula (II):
wherein X is Br or Cl; each of ℓ and m is an integer of 1 to 4; n means that the number of repeating units is 1 to 50; each of R' and R 2 is a C 1-12 alkyl group; and each of R 3 and R 4 is a hydrogen atom, a lower alkyl group, an alkylphenyl group or a phenyl group, the total amount of (A) and (B) being 2 to 40 parts by weight. This composition has excellent heat resistance and excellent heat stability in addition to flame retardancy.
