Beschreibung
Zusammenfassung:	An adhesive composition comprising a copolymer of propylene and at least one comonomer selected from the group consisting of ethylene and C4-20alpha-olefins, the copolymer having (i) a content of units derived from propylene of greater than about 50 mole percent, (ii) a Brookfield viscosity at 190 C from about 50 to about 100,000 cP, (iii) an MWD from about 1.5 to about 15, and (iv) containing less than about 50 ppm residual catalyst metal.
