ABSTRACT:
A terminal-modified block copolymer having the remainder of an amino group or imido group-containing a terminal-treating agent bonded to the polymer terminal which is obtained by treating the active terminal of a block copolymer comprising conjugated dienes and vinylaromatic hydrocarbon compounds, which is obtained by using as the polymerization initiator at least one member selected from alkali metals or organoalkali metals and has a vinylaromatic hydrocarbon content of 5 to 95% by weight and a number average molecular weight of 5,000 to 1,000,000 with at least one terminal-treating agent selected from imide compounds, cyanamide compounds, aziridinyl compounds, amide compounds, or tertiary amino group-containing compounds other than the compounds. An adhesive composition is disclosed having excellent tackiness, adhesiveness, and creep resistance characteristics which comprises the block copolymer and a tackifier resin, a water-absorbing composition comprising the block copolymer and a highly water-absorbing resin. A thermoplastic resin composition is disclosed comprising the block copolymer and a thermoplastic resin, and an electroconductive composition is disclosed comprising the block copolymer and an electroconductive material.
