摘要： A high impact strength random block copolymer including (a) about 65- 97 wt.% of a crystalline propylene/ethylene copolymer A containing from about 0.5 wt.% to about 6 wt.% derived from ethylene and from about 94 wt.% to about 99.5 wt.% derived from propylene, and (b) about 3 - 35 wt.% of a propylene/ethylene copolymer B containing from about 8 wt.% to about 40 wt % derived from ethylene and from about 60 wt% to about 92 wt.% derived from propylene. The crystalline to amorphous ratio Lc/La of the random block copolymer ranges from about 1.00 to about 2.25. The random block copolymer is characterized by both high toughness and low haze.
