Patent number: 4533700Abstract: 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.Type: GrantFiled: January 19, 1984Date of Patent: August 6, 1985Assignee: Mitsui Petrochemical Industries Ltd.Inventors: Kinya Mizui, Masami Takeda, Tadao Iwata

Patent number: 4433100Abstract: Synthetic resins suitable for use in printing ink compositions are produced by reacting a mixture consisting essentially of (a) a predominant amount of dicyclopentadiene and lesser amounts of (b) at least one hydrocarbon selected from the group consisting of monoolefins, diolefins, and polyenes each having more than five carbon atoms, and having no aromatic rings, and (c) at least one member selected from the group consisting of fatty acid-containing materials and rosin acid-containing materials. Additional synthetic resins suitable for use in printing ink compositions are produced by reacting components (a) to (c) above with an ethylenically unsaturated lower aliphatic dicarboxylic acid or anhydride, such as maleic anhydride.Type: GrantFiled: July 16, 1982Date of Patent: February 21, 1984Assignee: Neville Chemical CompanyInventor: James J.
