Supertransparent high impact strength random block copolymer |
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. |
