Elastomeric polypropylene and process for its production. Du Pont, January 24, 1979: GB2001080-A (6 worldwide citation)

A fractionable, elastic polypropylene has an inherent viscosity of 1.5 to 9, exhibits no yield point, a tensile set not exceeding 150% and contains 10 to 80% by weight of a diethyl ether- soluble fraction having an inherent viscosity exceeding 1.50 by weight and exhibits birefringence when a film fo ...
