Abstract

PURPOSE: To enhance melt-flow characterisitcs of a modified block copolymer obtd. and to decrease gel content thereof, by the addn. of an unsaturated dicarboxylic or a deriv. thereof with a vinyl arom. cpd.-conjugated diene cpd. block copolymer.
CONSTITUTION: A suitable amt. of an unsaturated dicarboxylic acid or a deriv. thereof is added with the conjugated diene portion of a vinyl arom. cpd.-conjugated diene cpd. block copolymer contg. 5W70wt% vinyl arom. cpd. so as to obtain a modified block copolymer contg. 0.5wt% or less toluene-insol. component. Said modified block copolymer is suitable for modification of a resin in addition to use for an adhesive, becuase of a small gel content.
