Abstract
A polybutylene based hot melt adhesive composition having a variety of end uses, particularly in construction and elastic attachment applications for nonwoven articles such as disposable diapers. Unlike typical hot melt adhesives, the present composition can withstand high peel and shear loads at elevated temperatures for extended periods of time without experiencing catastrophic bond failure. The composition includes polybutylene polymer or a mixture of polybutylene and polyolefin polymers, and a stabilizer, with the remaining ingredients chosen from one or more of a polyolefin polymer, a tackifier resin, a plasticizer, or a wax. The hot melt adhesive composition can be applied using common application techniques such as extruding or spraying.
