Patent ID: 7655720

Claim:
A hot melt adhesive comprising a radial block copolymer component comprising (PS-PI-PB) n X wherein PS is polystyrene, PI is polyisoprene and PB is polybutadiene, X is the residue of a multifunctional coupling agent used in the production of the radial block copolymer, and n is equal to or greater than 3 and represents the number of PS-PI-PB arms appended to X, and wherein the styrene content of the radial block copolymer is from 25 wt %, to about 50 wt %, a linear triblock copolymer, a tackifying resin, a liquid plasticizer, and, a wax, wherein, based on the weight of the adhesive composition, the said radial block copolymer component is present in amounts of less than 15 wt %, the linear triblock copolymer is present in amounts of up to about 20 wt %, the tackifying resin is present in amounts of from about 30 to about 70 wt % the plasticizer is present in amounts of less than about 20 wt % and the wax is present in amounts of 0 wt % up to about 5 wt %, said adhesive being suitable for use as an elastic attachment adhesive.
