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.
Claims15
A hydrocarbon resin consisting essentially of a copolymer of (A) at least one unsaturated hydrocarbon selected from the group consisting of (i) unsaturated chain hydrocarbons and (ii) cyclic hydrocarbons having vinylidene group and (B) at least one compound selected from the group consisting of 9,10-dihydrodicyclopentadiene and its derivatives, the amount of the polymerization unit of component (A) in the copolymer being 20 mol% to 98 mol% and that of component (B) in the copolymer being 80 mol% to 2 mol%.
