Abstract:
A hot melt pressure-sensitive adhesive (HMPSA) composition, comprising:(a) one or more styrene-butadiene (SB) block copolymers;(b) one or more styrene-isoprene-styrene (SIS) block copolymers, or a mixture of SIS and styrene-isoprene (SI) block copolymers; and(c) a tackifying component having a ring and ball softening point of from about 35 to 60.degree. C. and an aromatic content of from about 5 to 25% by weight, made by copolymerizing at least one C.sub.5 monolefin or diolefin with at least one C.sub.8 or C.sub.9 monoalkenyl aromatic hydrocarbon; andwherein the weight ratio of (a):(b) ranges from about 0.5:1 to 2:1.
