ABSTRACT:
The hot-melt adhesives of the present invention comprise a blend of at least one propylene/C.sub.4 to C.sub.10 higher 1-olefin copolymer having an acid number of at least 5, a tackifying resin, and a high density, low viscosity polyethylene wax having a melt viscosity of about 5 to 50 cp. at 150.degree. C. This hot-melt adhesive has a novel combination of properties including low melt viscosity and fast setting which meet the requirements necessary for use in rapid bonding or closing in low and high temperature applications.
