Abstract

PURPOSE:To obtain a composition outstanding in blocking resistance, giring high-performance adhesive mass when incorporated with tackifier etc., by blending three kinds of aromatic vinyl-conjugated diene block copolymer each prepared by coupling with specific coupling agent. CONSTITUTION:The objective composition made up of (A) 20-60wt.% of a block copolymer of formula I [A is aromatic vinyl (ref. styrene) polymer block with a molecular weight of 10,000-30,000; B1 is conjugated diene (pref. isoprene) polymer block; l1 is 1-3; m is 2-4; Y1 is coupling agent other than tin-based ones (pref. halogenated silicon compound)], (B) 50-10wt.% of a second block copolymer of formula II (B2 is the same as B1; l2 is the same as l1; n is the same as m; Y2 is tin-based coupling agent) and (C) 10-50wt.% of a third block copolymer of formula III (B3 is similar to B2, molecular weight being >=1.2 times that of B2; l3 is the same as l1). When this composition is to be used as an adhesive mass, 100pts.wt. of said composition is incorporated with 20-300 pts.wt. of a tackifier and 0-200pts.wt. of a softening agent.
