Abstract:
A composition comprising a mixture of propylene polymers, consisting offrom 15 to 85% by weight of a propylene polymer (A) whose isotactic index is at least 0.95 and which contains only monomeric units derived from propylene, and from 85 to 15% by weight of a block copolymer (B) which consists of a first block of from 55 to 85% by weight relative to the total weight of block copolymer (B) chosen from crystalline propylene polymers and of a second block of from 45 to 15% by weight relative to the total weight of block copolymer (B) chosen from propylene-ethylene copolymers including from 30% to 70% by weight relative to the weight of the second block of ethylene, the said block copolymer (B) having a fraction soluble in n-decane, measured at 23.degree. C., of at least 16% by weight.
