PURPOSE:To impart a high thermal stability to the title compsn. comprising a specific composite resin contg. a Br flame retardant by adding a specific compd. to the compsn. CONSTITUTION:The title compsn. which comprises a composite resin consisting of a styrenic resin (e.g. ABS) and a polycarbonate resin and contg. a Br flame retardant (e.g. tetrabromobisphenol A carbonate oligomer) is stabilized by adding at least one compd. selected from the group consisiting of (anhydrous) boric acid, a borate of a group II or III metal, a boron compd. having a group of the formula, and hydrotalcite (e.g. orthoboric acid) to the compsn. |
