Claims20
An absorbent article comprising a liquid permeable interior layer, a liquid impervious exterior layer, and an absorbent layer therebetween;
- further comprising a hot melt adhesive composition consisting essentially of:
- (i) an amorphous polyolefin composition comprising more than 40% 1-butene;
- and
- (ii) a second amorphous polymer comprising at least one butane monomer, the polymer having a molecular weight (MWn) of at least 1000 wherein the polymer is compatible with the polyolefin.
1 more element
A disposable absorbent article comprising a first substrate, a second substrate, and a hot melt adhesive composition bonding the first substrate and the second substrate to one another, wherein the hot melt adhesive consists essentially of:
- (i) an amorphous polyolefin composition comprising more than 40% 1-butene;
- and
- (ii) a second amorphous polymer comprising at least one butane monomer, the polymer having a molecular weight (MWn) of at least 1000 wherein the polymer is compatible with the polyolefin.
