PURPOSE:To obtain the subject molding resin composition having excellent mechanical strength, heat-resistance and moldability by uniformly mixing a polyamide resin, a thermoplastic polyester resin, a specific modified polyoctenamer and optionally glass fiber. CONSTITUTION:The objective composition is composed of (A) 70-99.5% of a resin mixture consisting of (a) 5-95wt.% of a polyamide resin (preferably nylon 6, nylon 12, etc.) and (b) 95-5wt.% of a thermoplastic polyester resin (preferably polyethylene terephthalate or polybutylene terephthalate) and (B) 0.5-30wt.% of a modified polyoctenamer produced by polymerizing 19-1wt.% of an alpha,beta-unsaturated carboxylic acid compound and 19-1wt.% of an unsaturated epoxy compound in the presence of 80-98wt.% of a polyoctenamer and having a number- average molecular weight of preferably 50,000-200,000. As necessary, 50-90wt.% of the above composition is compounded with 50-10wt.% of glass fiber. |
