(여기에서, R은 수소 또는 탄소수 1-5의 알킬기이고, R-R는 각각 수소, 탄소수 1-5의 알킬 또는 할로겐이다.)로 표시되는 분기제로부터 유도된 분기핵 구조를 갖으며 점도 평균 분자량이 15,000-40,000이고, 그 아세톤 가용분이 3.5중량% 이하인 분기 폴리카르보네이트 1-99중량% 및 스티렌계 수지, 폴리아미드 수지, 폴리올레핀, 고무상 탄성체로부터 선택된 적어도 1종의 중합체 99-1중량%로 되어 있는 폴리카르보네이트 수지 조성물은 각종 성형품(예를들면, 자동차, 가전제품, OA 등의 공업재료), 특히 블로우 성형품의 소재로서 유효하게 이용된다. A polycarbonate resin composition comprising 1 to 99% by weight of a branched polycarbonate having a branched nucleus structure derived from a branching agent represented by the general formula: wherein R is a hydrogen atom or an alkylgroup having 1 to 5 carbon atoms, and R to R are are hydrogen atoms, alkyl groups having 1 to 5 carbon atoms or halogen atoms, respectively, a viscosity average molecular weight of 15,000 to 10,000, and an acetone-soluble matter of not more than 3.5% by weight; and 99 to 1% by weight of at least one selected from the group consisting of styrene rein, polyamide resin, polyolefin and rubber-like elastomer is disclosed. The above-mentioned polycarbonate resin composition is utilized effectively as the material for various molding products such as industrial materials for automobiles, home electric appliances, and office automation appliances.
