POLYACETAL RESIN COMPOSITION/THERMOPLASTIC ELASTOMER COMPOSITE MOLDING AND METHOD FOR MOLDING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a composite molding having an improved fusion bondability of an interface between a molding site made of a polyacetal resin having improved fusion bondability and a molding site made of a thermoplastic elastomer. SOLUTION: The composite molding is obtained by fusion bonding the molding site made of a polyacetal composition and a molding site made of the thermoplastic elastomer. The polyacetal composition is obtained by blending 1 to 100 pts.wt. of a polyalkylene terephthalate (having 2-4C alkylene group) copolymer having a melt flow temperature of 210 deg.C or lower and 0.1 to 15 pts.wt. of at least one compound selected from the group consisting of a core shell polymer (a) having a shell of a polymer made of a core of a rubber-like polymer and vinyl copolymer, an isocyanate compound (b), an isothiacyanate compound (c) and a modified material (d) of the compound (b) or (c) with 100 pts.wt. of the polyacetal resin.
