Polymer blocks A are non-elastomeric blocks which as homopolymers have glass transition temperatures above 20°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.
