ABSTRACT:
Hot-melt adhesive compositions used in non-woven assemblies, comprising:(a) 100 parts by weight of a block copolymer of the formula S-(I/B)-S, wherein S represents a predominantly poly(styrene) block and (I/B) represents a polymer block obtained by at random copolymerization of a mixture of predominantly isoprene and butadiene in a weight ratio in the range of from 70:30 to 30:70, wherein the total block copolymer has a melt flow index measured at 200° C./5 kg in the range of from 0.1 to 12 g/10 min. and has a poly(styrene) content of from 28 to 50 wt % and a coupling efficiency of from 50 to 100%,(b) from 250 to 300 parts by weight of a tackifying resin,(c) from 50 to 150 parts by weight of a plasticizer, and(d) from 0 to 3 parts by weight of auxiliaries, such as stabilizers and/or antioxidants,and disposable articles, comprising at least a non-woven element and assembled by the use of said hot-melt adhesive compositions.
