BLENDS OF POLYPROPYLENE WITH HYDROGENATED HYDROCARBON RESINS

摘要

Blends of polypropylene with hydrogenated polymers and copolymers of styrene. The useful polymers have a precisely defined molecular weight distribution and must be hydrogenated to the point where at least 50 percent of the aromatic unsaturation is reduced. The blends are useful in preparation of heat sealable films and capacitor dielectrics.
