摘要:
Soft propylene-based resin compositions, which comprise substantially the following block (I) and block (II): Block (I): propylene-based polymer having propylene unit chain segments that bond in a mode of head-to-tail bonding, in which the chain segment has an isotactic block-containing stereoblock structure; Block (II): copolymer containing at least propylene and ethylene, exhibit good flexibility, transparency, and heat resistance.
