ABSTRACT:
A synthetic resin composition, having a high toughness and a wear resistance, comprises a synthetic resin with solubility parameter .delta.9.5 cal1/2 cm.sup.31 3/2 or higher and a modifier with solubility parameter .delta.8.5 cal.sup.1/2 cm.sup.-3/2 or lower and dispersed therein, characterized in that a silicon containing copolyester, being a block copolymer consisting of 1.about.90% by weight of siloxane segment represented by the undermentioned general formula (A) and 99.about.1% by weight of polyester segment represented by the undermentioned general formula (B), the degree of polymerization of siloxane segment being 1.about.2,000, and that of polyester segment 1.about.1,000, is added to be mixed therewith as a dispersibility improver: ##STR1## (In this formula, m denotes a number of 1.about.2,000.) ##STR2## (In this formula, R.sub.1 designates one or two or more members selected from among aromatic divalent radicals having 6.about.12 carbon atoms or aliphatic divalent radicals having 4.about.20 carbon atoms, and R.sub.2 from among aromatic divalent radicals having 6.about.20 carbon atoms or aliphatic divalent radicals having 2.about.20 carbon atoms; and n stands for a number of 1.about.1,000).
