Abstract
A hot melt adhesive material and articles made using the hot melt adhesive to assemble structures in an article. The adhesive material typically is manufactured by blending amorphous polymer with a compatible amorphous polymer.
Claims25
A hot melt adhesive composition consisting essentially of:
- (i) an amorphous polyolefin copolymer composition comprising more than 40 mole % 1-butene;
- and
- (ii) a second amorphous polymer comprising at least one butene monomer, the polymer having a molecular weight (MWn) of at least 1000 wherein the polymer is compatible with the polyolefin.
(canceled)
A hot melt adhesive composition comprising:
- (i) about 90 to 10 wt. % or more of an amorphous polyolefin composition comprising a copolymer having more than 40 mole % 1- butene;
- (ii) the balance comprises a polyisobutylene;
- wherein the adhesive is substantially free of a tackifier.
(canceled)
A hot melt adhesive composition consisting essentially of:
- (i) a blend of amorphous polyolefin copolymers, each copolymer composition comprising more than 40 mole % 1-butene;
- and
- (ii) a second amorphous polymer comprising at least one butene monomer, the polymer having a molecular weight (MWn) of at least 1000 wherein the polymer is compatible with the polyolefin.
