Document Type and Number:
Japanese Patent JP3986655
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain an aromatic polycabonate resin composition excellent in transparency, releasing properties useful for moldings or the like by making the composition include a specific polysiloxane in a specific ratio to the aromatic polycarbonate resin. SOLUTION: This composition comprises (A) 100 pts.wt. of the aromatic polycarbonate resin and (B) 0.01 to 3 pts. of polysiloxane including phenyl group and the constituent (B) includes at least a phenyl siloxane unit expressed by formula I (R<1> is an 1 to 4C alkyl; x is 0 to 2) and a trialkylsiloxane unit expressed by formula II (R<2> is R<1> ), and the ratio of the aliphatic hydrogen to aromatic hydrogen is 2.4 to 5.0, and the viscosity of the constituent (B) is 1 to 2000 cSt at 25 deg.C. The phenyl group including polysiloxane of the constituent (B) preferably includes an alkylphenylsiloxane unit expressed by formula III (R<3> is an 1 to 6C alkyl, a cycloalkyl).
