Abstract:
A polymer blend includes a first random copolymer of propylene and one or more C-Cα-olefins other than propylene having a melting point of above 116 C. and up to about 145 C. and which constitutes from about 60 weight percent to about 95 weight percent of the composition, and a second random copolymer of propylene and one or more C-Cα-olefins other than propylene having a melting point of from about 70 C. to no more than 116 C. and which constitutes from about 5 weight percent to about 40 weight percent of the composition. The polymer blend includes a xylene soluble fraction having a weight average molecular weight of above about 100 kg/mol and an intrinsic viscosity of above about 1.0 dl/g.
