DISPOSABLE ARTICLE CONSTRUCTIONS

摘要

A hot melt pressure sensitive adhesive composition comprises 1535% of an A-B-A block or multiblock A-B-A-B-A-B copolymer, 45-70% of a compatible tackifying resin, 5-30% of a plasticizing oil, 0-5% of a petroleum derived wax, and 0.1-2% of a stabilizer. Polymer blocks A are non-elastomeric blocks which as homopolymers have glass transition temperatures above 20.degree.C; polymer block B is butadiene or hydrogenated butadiene. They are used in disposable articles such as diapers to bond the polyethylene or polypropylene substrates of multi-line type construction to the tissue, non-woven polyethylene or polypropylene substrates.
