Abstract
Abstract an oil-free, pressure sensitive adhesive composition comprises a monoalkenyl arene/isoprene block copolymer, a tackifying resin compatible with the isoprene block and a predominately aromatic second resin compatible with the monoalkenyl arene block. These adhesive compositions possess excellent adhesive properties along with a lower melt viscosity and lower cost.
