| abstract |
A polycarbonate-polyorganosiloxane copolymer comprising a repeating unit I represented by the general formula: <IMAGE> (I) a repeating unit II represented by the general formula: <IMAGE> (II) a structural unit III represented by the general formula: <IMAGE> (III) and a terminal group IV of polyhalogenophenoxy group represented by the general formula: <IMAGE> wherein symbols in the formulae are the same as those described in the specification, is disclosed. Content of the repeating unit II based on the total of contents of the repeating unit I and the repeating unit II and content of the structural unit III based on the total of contents of the repeating unit I, the repeating unit II and the structural unit III are in specific ranges, respectively. Resin compositions comprising the polycarbonate-polyorganosiloxane copolymer and a resin, such as a polycarbonate, a fluororesin, a styrenic resin and the like, inorganic filler or pigment is also disclosed. The copolymer and the resin composition comprising said copolymer have excellent flame resistance, impact resistance, transparency and mold releasing property. They have also excellent flow property, sliding property or solvent resistance. |
