Abstract

Compatibility and viscoelasticity in non-solvent type pressure sensitive adhesive of styrene-isoprene-styreno(SIS) block copolymer with tackifier resin were investigated. In the isoprene phase of SIS block copolymer, it was found that it's compatibility with $C^5$ petroleum resin was good, but that with Coumarone-indents resin was not so good. The magnitudes of peel strength, tack, and holding power were as follows : $C^5$ petroleum resin>rosin ester resin>coumarone-indene resin. The tackifier resin with good compatibility in rubber phase was also effective. However, with plateau modulus value of $1{\times}10^6-3{\times}10^6dyn/cm^2$, the effect of pressure sensitive adhesives was excellent.
