Abstract:
A propylene composition comprising (percent by weight): A) 60%-90%, of a crystalline propylene copolymer containing from 3.5% to 10% of ethylene derived units and having a melting temperature Tm (measured by DSC on the as-reactor polymer) ranging from 146° to 160° C.; B) 10%-40%, of a copolymer of propylene containing from 15% to 30%, of ethylene derived units.
