Abstract

PURPOSE:To obtain the title copolymer excellent in melt flow and moldability as well as in skin and gloss of a molding, comprising an ethylene/alpha-olefin/5- alkenyl-2-norbornene copolymer having a specified structure and specified properties. CONSTITUTION:The title amorphous or lowly crystalline copolymer comprises 40-96mol.% ethylene, 60-4mol.% 3-20C alpha-olefin and 0.01-0.7mol.% 5- alkenyl-2-norbornene, having an intrinsic viscosity eta of 0.5-10dl/g as measured in decalin at 135 deg.C, an MW distribution (Mw/Mn) of 2-16, a melt flow rate MFR of 0.01-1,000g/10min as measured at 230 deg.C under a load of 2.16kg, satisfying the relationship of formula I between said eta and said MFR and satisfying the relationship of formula II of the molar ratio between the 5-alkenyl-2- norbornene component and the double bonds derived from the alkenyl groups of this component. This copolymer is excellent in melt flow and moldability as well as in skin and gloss of a molding and low in stickiness of the surface of a molding and can give a thermoplastic resin composition excellent in an effect of improving impact resistance and in the above-mentioned properties when used as a modifier for a thermoplastic resin.
