Abstract
The object of this invention is to provide polycarbonate resin compositions. PA0 (A) 30-80 parts by weight of a copolyester carbonate containing constituent units having the formula: ##STR1## and the formula: ##STR2## (where R and R' independently represent halogen atoms, monovalent hydrocarbon groups or hydrocarbonoxy groups; W is a divalent hydrocarbon group, --S--, --S--S--, --O--, --S(.dbd.O)--, --(O.dbd.)S(.dbd.O)-- or --C(.dbd.O); n and n' independently represent integers from 0 to 4; X is a divalent aliphatic group having 6-18 carbons; and b is 0 or 1) or this and a polycarbonate resin, and PA0 (B) 70-20 parts by weight of aromatic polyester resin, and which contains also: PA0 (C) 60-1 parts by weight of inorganic filler per 40-99 parts of (A)+(B).
