Document Type and Number:
Japanese Patent JP5375907
Kind Code:
B2
Abstract:
There is provided an aromatic polycarbonate resin composition which is free from unevenness of color and exhibits a good heat resistance and a good hydrolysis resistance. The aromatic polycarbonate resin composition of the present invention comprises:
(a) 100 parts by weight of an aromatic polycarbonate resin having a viscosity-average molecular weight of not less than 16000 and containing a branched constitutional unit in an amount of 0.3 to 0.95 mol% on the basis of a constitutional unit represented by the general formula (1):
(wherein X is a single bond, an alkylene group having 1 to 8 carbon atoms, an alkylidene group having 2 to 8 carbon atoms, a cycloalkylene group having 5 to 15 carbon atoms, a cycloalkylidene group having 5 to 15 carbon atoms, or a divalent connecting group selected from the group consisting of -O-, -S-, -CO-, -SO- and -SO 2 -);
(b) 0.00001 to 0.05 part by weight of at least one colorant selected from the group consisting of phthalocyanine-based compounds, anthraquinone-based compounds and ultramarine blue; and
(c) 0.0001 to 0.5 part by weight of a polyalkyleneglycol compound having a number-average molecular weight of 62 to 4000, which is represented by the general formula (2):
(wherein R 1 , R 2 , R 3 and R 4 are independently a hydrogen atom or an alkyl group, and m is a natural number of 1 to 1000).
