Styrene-isoprene-styrene block copolymer composition for low viscosity low application temperature hot melt adhesives

Abstract

A low viscosity low application temperature hot melt adhesive which contains a predominantly branched styrene-isoprene-styrene block copolymer composition comprised of linear polymeric blocks wherein the polystyrene block molecular weight is greater than 12,000, the polystyrene content is 35% or less by weight of the block copolymer composition and the molecular weight of the block copolymer composition and the coupling efficiency are chosen so that the melt viscosity of the adhesive made with the composition is less than 3100 cps.
