| 摘要 |
The present invention is directed to a low viscosity, high tensile strength adhesive of the hot melt pressure sensitive type composition comprising: (a) from about 15 to about 30% by weight of an A-B-A block or A-B-A-B-A-B- multi-block copolymer containing from about 35 to about 55 parts styrene per 100 parts polymer where polymer blocks A are styrene blocks and polymer blocks B are butadiene or hydrogenated butadiene; (b) 70 to about 85% by weight to a composition tackifying resin; and (c) 0.1 to about 1.5% by weight of a stabilizer. Because the adhesive of the present invention has low viscosity and high tensile strength at both high and low temperatures, the adhesive formulation of the present invention is particularly well-suited to disposable diaper construction, hinge binding in books, PET bottle labeling, and attaching base cups to PET beverage bottles.
