摘要： A flame-retardant resin composition which comprises (A) 100 parts by weight of a resin ingredient (component (a)) comprising at least 50 wt.% impact-resistant polystyrene and (B) 1 to 50 parts by weight of a phosphorus compound (component (b)) represented by the formula (I). In the formula, A and A' are the same or different and each represents -OR or -Q, wherein R and Q each represents C1-12 alkyl, C5-10 cycloalkyl, C7-20 aralkyl, or C6-15 aryl. The polystyrene resin composition and a molded article thereof contain substantially no halogens and have heat resistance, in particular, a high level of deflection temperature under load.

摘要： A flame retardant resin composition comprising:

(A) 100 parts by weight of a resin component (component a) containing at least 50% by weight of a high impact polystyrene, and
(B) 1 to 50 parts by weight of a phosphorus-containing compound (component b) represented by the following general formula (I):

wherein A and A' are the same or different and represent -OR or -Q wherein R and Q represent an alkyl group having 1 to 12 carbon atoms, a cycloalkyl group having 5 to 10 carbon atoms, an aralkyl group having 7 to 20 carbon atoms or an aryl group having 6 to 15 carbon atoms.
According to the present invention, there are provided a polystyrene resin composition containing substantially no halogen and having heat resistance, particularly a high heat distortion temperature under load, and an article molded from the composition.
