Patent ID: 8455589

Claim:
A propylene polymer comprising a blend of a component having a crystallinity of 10% or less and a component having a crystallinity of 20% or more, said propylene polymer having: a) a melting point of X° C. or more where X=−0.0038(Tp) 2 +0.36(Tp)+150, where Tp is the temperature of polymerization in ° C., and wherein the polymer has a melting temperature of 150° C. or higher; b) an Mw of 10,000 g/mol or more; c) a heat of fusion of from 1-70 J/g; d) stereodefects per 10,000 monomer units of Y or less where Y=2.35(Tp)−100 (where Tp is the temperature of polymerization in ° C.) for the portion of the blend that is insoluble in hexane at 23° C.; e) a dot T-Peel on Kraft paper of 1 N or more; and f) a branching factor of 0.98 or less, where the branching factor is the ratio of g′ measured at Mz to g′ measured at Mw.
