Document Type and Number:
Japanese Patent JP4595140
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain both a new propylene-based copolymer capable of providing a thermoplastic resin composition having excellent flexibility, transparency, resistance to flexural whitening, resistance to damage and heat resistance by blending the copolymer with a resin such as a polypropylene and a thermoplastic resin composition comprising the propylene-based copolymer and a thermoplastic resin. SOLUTION: This propylene-based polymer characteristically comprises a copolymer composed of propylene, one or more kinds of olefins selected from 2-20C olefins except propylene and a cyclic olefin in which the total number of carbons of the monomer components except the cyclic olefin is >=7.
