PURPOSE:To provide a resin compsn. which has a high viscosity and gives moldings having excellent mechanical properties by extrusion or blow molding, consisting of a polyether esteramide and an olefin copolymer. CONSTITUTION:A polyether esteramide composed of 6C or higher aminocarboxylic acid (e.g. 11-aminoundecanoic acid), lactam or a salt of 6C or higher diamine and dicarboxylic acid (a), a poly(alkylene oxide)glycol (b) having a number-average MW of 300-6,000 and a 4-20C dicarboxylic acid (c) (e.g. terephthalic acid), and an olefin copolymer composed of alpha-olefin (x) (e.g. ethylene) and a glycidyl ester of an alpha,beta-unsaturated acid (y) (e.g. glycidyl methacrylate), are used. 50-99wt% said polyether esteramide is melt-kneaded with 50-1wt% said olefin copolymer at 100-300 deg.C. |
