摘要： The partially cross-linked polymer composition of the present invention is obtainable by dynamically heat-treating: 95 to 50% by weight of a resin (A) comprising an ethylene copolymer containing 5 to 48% by weight of units derived from at least one monomer selected from vinyl acetate, (meth)acrylic acid, (meth)acrylate ester, glycidyl (meth)acrylate and carbon monoxide, and 5 to 50% by weight of a resin (B) having a melt viscosity (JAI 7-1991) at 180°C of over 10,000 mPa·Es and comprising a two or more-competent propylene copolymer containing 0.1 to 20% by mol of units derived from α-olefins other than propylene, or a blend of the two or more-component propylene copolymer and a propylene homopolymer in the presence of an organic peroxide (C) in an amount of from 0.001 to 4 parts by weight based on 100 parts by weight of the total amount of the resins (A) and (B). The invention can provide the polymer compositions having excellent fluidity and productivity, which allow to produce molded articles with heat resistance, adhesion with paint, tensile strength, flexibility, stress crack resistance, and RF weldability, such as molded articles for automobile exterior trim, and can provide the process for producing the polymer compositions.
