ABSTRACT:
Blends of low styrene content polystyrene-polyisoprene-polystyrene block copolymer and high styrene content polystyrene-polyisoprene-polystyrene block copolymer can be used with tackifier resins, plasticizer oil and antioxidants to formulate pressure sensitive adhesives of improved cohesive strength vis-a-vis adhesives formed from the low styrene content polystyrene-polyisoprene-polystyrene block copolymer while maintaining good balance between tack, bonding characteristics and heat resistance.
