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.

Supertransparent high impact strength random block copolymer

Propylene polymers have a molecular weight ratio Q (M.sub.w /M.sub.n) of from 6 to 30 and are obtainable by Ziegler-Natta polymerization in the presence of hydrogen as molecular weight regulator and are particularly suitable for the production of films and moldings.
