Zusammenfassung: | The present invention relates to a polycarbonate and copolyester alloy resin composition which shows flame resistance and has improved transparency, chemical resistance, heat resistance and impact resistance. The polycarbonate and copolyester alloy resin composition includes: (A) 60-95 wt% of polycarbonate; (B) 5-40 wt% of copolyester containing a dicarboxylic acid ingredient and a diol ingredient; and (C) 5-30 parts by weight of a solid-phase polymer flame retardant based on 100 parts by weight of the total weight of ingredients (A) and (B), wherein the dicarboxylic acid ingredient contains a terephthalic acid residue, the diol ingredient contains a 1,3-cyclohexanedimethanol residue or a terephthalic acid residue and a 2,2,4,4-tetramethyl-1,3-cyclobutanediol residue.
난연성이 부여되면서 투명성 및 내화학성과, 내열성 및 내충격성이 향상된 폴리카보네이트 및 코폴리에스테르 얼로이 수지 조성물이 개시된다. 본 발명은 (A) 폴리카보네이트 60 내지 95 중량%; (B) 디카르복실산 성분과 디올 성분을 포함하는 코폴리에스테르 5 내지 40 중량%; 및 (C) 상기 (A) 및 (B) 성분 총 100 중량부에 대하여 고상형의 고분자 난연제 5 내지 30 중량부;를 포함하되, 디카르복실산 성분은 테레프탈산 잔기를 포함하고, 상기 디올 성분은 1,3-사이클로헥산디메탄올 잔기 또는 1,4-사이클로헥산디메탄올 잔기와, 2,2,4,4-테트라메틸-1,3-사이클로부탄디올 잔기를 포함하는 폴리카보네이트 및 코폴리에스테르 얼로이 수지 조성물을 제공한다. |
