Patent Images
1. 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.
