Polypropylene-based adhesive compounds

摘要

A copolymer comprising units derived from propylene and at least one comonomer selected from the group consisting of ethylene and C 4-20 ±-olefins, the copolymer having (i) a content of units derived from propylene of greater than about 50 mole percent, (ii) a Brookfield viscosity at 190C from about 50 to about 100,000 cP, (iii) an MWD from about 1.5 to about 6, and (iv) containing less than about 50 ppm metal.
