PURPOSE:To obtain the titled composition significantly improved in both mechanical strength and hot water resistance, by incorporating a polyester resin with specific epoxy-modified silicone resin. CONSTITUTION:The objective composition can be obtained by incorporating (A) 100pts. by wt. of a polyester with (B) 0.5-10 (pref. 1-5)pts. by wt. of an epoxy-modified silicone resin with an epoxy equivalent 200-1,500 of formula (R<1>, R<2> and R<3> are each H or 1-20C hydrocarbon; X is organic group having monovalent epoxy, a and b are each contents of the structrual units, being 5-100) (e.g. a copolymer from phenylmethylsiloxane, dimethylsiloxane, monophenylsiloxane, phenylmethylsiloxane plus dimethylsiloxane). |
