POLYMER COMPOSITION AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polymer composition excellent in flowability and capable of preparing a molded product excellent in heat resistance, tensile strength characteristic and high frequency welding property, and a method for producing the same easily, at a low cost and by an excellent productivity. SOLUTION: This polymer composition is obtained by dynamically heat-treating (A) a resin consisting of at least 1 kind of an ethylene-based copolymer selected from a copolymer of a specific ethylene-a vinyl ester copolymer and a specific ethylene-an unsaturated carboxylic acid copolymer and (B) a resin consisting of a specific multicomponent propylene copolymer of≥2 components or a blended material of the propylene copolymer with a propylene homopolymer in the presence of a specific amount of (C) an organic peroxide.
