ABSTRACT:
Disclosed herein is a polymer composition, its manufacture and use, said composition may comprise greater than about 90 mole % propylene monomer, and having a unique combination of properties, including one or more of the following: a heat of fusion of more than about 108 J/g, a melting point of 165° C. or higher, a Melt Flow Rate so low that it is essentially not measurable and a molecular weight of greater than about 1.5×106. Further disclosed herein are blends or mixtures of the present novel polymer composition and products, such as, for example, microporous film structures and the like comprising same.
