Polycarbonate composition |
摘要 |
A thermoplastic resin composition is obtained by adding, to 100 parts by weight of a resin composition comprising polycarbonate (1)/styrenic resin (2) = 50/50 to 95/5 (% by weight), 0.1 to 20 parts by weight of a compatibilizing agent (3), if necessary together with a polyalkylene arylate resin (4) and/or a polyphenylene ether (5). Component (2) includes rubber-modified polystyrenic resins. The domains of component (2) dispersed in the matrix composed of component (1) are surrounded by component (3). Component (3) is a block copolymer (C) comprising a polystyrene block (A) and a terminally located polybutadiene block (B) with the double bond originating from butadiene being epoxidized. By adding an organophosphorus compound as flame retardant (6) and a fluororesin (7) as a flame retardant auxiliary (7), a halogen-free flame-retarded thermoplastic resin composition can be obtained. A polycarbonate-styrenic resin polymer blend improves flow characteristics and impact strength. |
