Abstract
An elasticated absorbent article has elastication provided by elastomeric hot melt adhesive compsn. comprising tackifying resin(s) and thermoplastic elastomer(s) selected from styrene/butadiene/styrene (SBS) block copolymers and their blends with styrene/isoprene/styrene (SIS) block copolymer in which SIS is present in an amt. not greater than 50 wt.% of the total block copolymer. The compsn. (a) is capable of bonding, when applied from the molten state, to materials selected from plastic and/or cellulosic materials, with a 90 deg peel force of not greater than 0.5 N/cm (as defined); (b) has a tensile strength retention after 50 cycles (as defined) of at least 40%; and (c) has a viscosity of not greater than 120,000 cps at 180 deg C and applied shear of 80 sec-1. Also claimed is an elasticated absorbent in which the elastication is provided by an elastomeric hot melt adhesive compsn. comprising: (1) 10-890 wt.% of a styrene block copolymer comprising at least two styrenic end blocks and at least one rubbery mid block per mol and contg. less than 40 wt.% of the total block copolymer of a block copolymer contg. only one styrenic block and one rubbery mid block per mol (diblock); (2) 20-90% of a tackifying resin compatible essentially only with the rubbery mid blocks; (3) 0-40% of a plasticiser(s); (4) 0-20% of an aromatic resin. The compsn. is further characterised in that: (a) is capable of bonding, when applied from the molten state, to materials selected from plastic and/or cellulose materials, with a 90 deg peel force of not less than 0.5 N/cm (as defined); (b) has a tensile strength retention after 50 cycles (as defined) of at least 40%; and (c) has a viscosity of not greater than 120,000 cps of 180 deg C and applied shear of 80 sec-1.
