摘要：
A hot melt adhesive composition that includes a first copolymer that includes the reaction product of a functionalized polyethylene, a propylene-alpha-olefin polymer that includes at least 50 mole % propylene and has a viscosity of no greater than 10,000 centipoise at 190° C., a ratio of z average molecular weight (Mz) to number average molecular weight (Mn) (Mz/Mn) of greater than 20, and a ratio of Mz to weight average molecular weight (Mw) (Mz/Mw) of greater than 3.0, and a free radical initiator.
