ABSTRACT:
A hydrocarbon resin consisting essentially of a copolymer of (A) an unsaturated chain hydrocarbon or a cyclic hydrocarbon having a vinylidene group and (B) 9,10-dihydrodicyclopentadiene or its derivative, or a hydrocarbon resin modified by addition reacting an ethylenically unsaturated carboxylic acid or its anhydride, or hydrogen, to the above-mentioned copolymer. The hydrocarbon resin and the modified hydrocarbon resin have a high softening point and a low melt viscosity, and are suitable for use in adhesives and traffic paints.
