Abstract
A polybutylene based hot melt adhesive composition having a variety of end uses, particularly in construction and elastic attachment applications on nonwoven disposable articles. Unlike typical hot melt adhesives, the present composition can withstand exposure to mineral oil and other oil based ointments without experiencing catastrophic bond failure. The composition includes polybutylene copolymer or a mixture of polybutylene and polyolefin polymers, a tackifier resin, a plasticizer, a wax and a stabilizer. The hot melt adhesive composition can be applied using common application techniques such as extruding or spraying.
