Abstract

A propylene-based polymer composition is characterized by a melt strength at 190° C. of at least 20 cN, a melt drawability at 190° C. of at least 100 mm/s, and a flexural modulus at room temperature of at least 240,000 psi. The propylene-based polymer composition includes a propylene-based polymer resin having a crystallinity of at least 50% coupled with a poly(sulfonyl azide).
