ABSTRACT:
A synthetic resin composition comprising 100 parts by weight of a synthetic resin, from 2 to 900 parts by weight of an inorganic filler, and from 0.02 to 20 parts by weight of a copolymer of a compound represented by formula (1) and maleic anhydride, maleic acid, a maleic acid salt or a maleic acid ester; ##STR1## wherein Z is a residue of a compound having from 2 to 8 hydroxyl groups; AO is an oxyalkylene group having from 2 to 18 carbon atoms; R.sup.1 is an unsaturated hydrocarbon group having from 2 to 5 carbon atoms; R.sup.2 is a hydrocarbon or acyl group having from 1 to 40 carbon; a is from 0 to 1,000, b is from 0 to 1,000, c is from 0 to 1,000, l is an integer of from 1 to 8, m is an integer of from 0 to 2, and n is an integer of from 0 to 7, l+m+n=2 to 8, al+bm+cn=1 to 1,000, and n/(l+n).ltoreq.1/3. In the synthetic resin composition the inorganic filler is uniformly dispersed in the synthetic resin with good efficiency at molding to give excellent molding characteristics and mechanical characteristics.
