PROBLEM TO BE SOLVED: To obtain a resin composition capable of being thermally crosslinked so as to show a melt viscosity high enough for blow molding or extrusion without causing conventional problems by mixing a polyester resin with a free radical generator selected from a 1,2-diphenylethane derivative and a diisopropylbenzene oligomer and a polyfunctional monomer. SOLUTION: This composition comprises 100 pts.wt. (A) polyester resin, 0.1-10 pts.wt. (B) free radical generator selected from a 1,2-diphenylethane derivative and a diisopropylbezene oligomer, 0.1-15 pts.wt. (C) polyfunctional monomer having at least two C-C double bonds, such as triallyl cyanurate, and at most 120 pts.wt. inorganic filler. The composition is crosslinked by heating to 220-320 deg.C to form a crosslinked product. Component B is exemplified by 2,3- dimethyl-2,3-dxiphenylbutane represented by formula I or a diisopropylbenzene oligomer represented by formula II. In the formulae, R1 to R4 are each hydrogen, a halogen, 1-5C alkyl, or the like; X and Y are each hydrogen, a 1-3C alkyl, or the like; and n is 2-50.
