ABSTRACT:
Disclosed are hot melt adhesives comprising ethylene/alpha-olefin copolymers prepared with either supported or unsupported metallocene-alumoxane catalysts for applications in hot melt adhesives used in automotive product assembly, packaging and food packaging. These ethylene copolymers have weight average molecular weight ranging from about 20,000 to about 100,000 and comonomer weight percent ranging from about 6 to about 30. The hot melt adhesive composition includes the ethylene copolymer and a compatible tackifier at a ratio of tackifier to copolymer of from 70:30 to 30:70 and may also include up to 30 weight percent of a paraffinic and microcrystalline wax of the copolymer and tackifier.
