摘要： An isoprene-based hydrocarbon resin having a softening point of from 60.degree. to 140.degree. C. and a number average molecular weight of from 500 to 2000 which is obtained by cationic polymerization of a monomer mixture comprising from 40 to 90% by weight of isoprene and from 10 to 60% by weight of an aliphatic monoolefin containing 4 to 10 carbon atoms in the presence of a Friedel-Crafts catalyst and an adhesive composition comprising 100 parts by weight of a base polymer selected from the group consisting of an amorphous propylene polymer, a block copolymer rubber and isoprene rubber and from 10 to 200 parts by weight of said isoprene-based hydrocarbon resin as a tackifier are disclosed. The isoprene-based hydrocarbon resin is excellent in hue and heat stability to provide an adhesive composition excellent in heat stability.
