摘　要：用不同种类增粘树脂、不同牌号苯乙烯-异戊二烯嵌段聚合物（简称SIS）制备SIS热熔压敏胶，考察不同种类增粘树脂、不同牌号SIS及萜烯树脂含量对SIS热熔压敏胶性能的影响，结果表明：萜烯树脂是改性SIS热熔压敏胶适宜的增粘树脂，当萜烯树脂在SIS热熔压敏胶中含量达50%时，SIS热熔压敏胶性能较佳，随不同牌号SIS中两嵌段SI含量的增加，SIS热熔压敏胶的剥离强度有所增加，持粘力有所下降。

Abstract：In this paper，styrene-isoprene-styrene block copolymer（SIS） hot-melt pressure sensitive adhesive（HMPSA） was prepared using different kinds of tackifying resins and SIS. Effects of tackifying resins，SIS and the amount of terpene-resin on the properties of SIS HMPSA were studied. The results showed that terpene-resin was a suitable tackifying resin to modify SIS hot-melt pressure sensitive adhesive. When the content of terpene resin in SIS HMPSA reached to 50%，the properties were better. AS the content of SI diblock in SIS increased，the peeling strength of SIS HMPSA increased，but constant adhesion decreased.

Key words：tackifying resin；SIS hot-melt pressure sensitive adhesive；terpene resin
