Abstract

Compositions comprising a mixture of propylene polymers consisting of from 15 to 85% by weight of a propylene polymer (A) whose isotactic index is at least 0.95 and from 85 to 15% by weight of a block copolymer (B) having a fraction soluble in n-decane, measured at 23.degree. C., of greater than 13% by weight.
