Abstract
Provided are a flame-retardant polycarbonate resin composition containing a phosphate compound as the flame retardant, and also injection moldings of the composition. The composition has good moldability, and its moldings have good phosphate mold-deposits resistance and good mold releasability. In particular, when containing a styrenic resin, the composition has much better melt fluidity, and its moldings have improved impact resistance and flame retardancy. The composition comprises 100 parts by weight of a resin or resin mixture of (A) from 20 to 100% by weight of a polycarbonate resin and (B) from 0 to 80% by weight of a styrenic resin, from 1 to 30 parts by weight of (C) a phosphate compound having a melting point of not lower than 70° C., and from 0.1 to 10 parts by weight of (D) at least one member selected from the group consisting of polyglycerins, polyalkylene glycols, esters of polyglycerins, esters of polyalkylene glycols and polyesters of polycarboxylic acids with polyalcohols.
