摘要： An epoxy resin composition comprising (a) a cyclopentadiene-type hydrocarbon resin having a hydroxyl value of 100 to 300 obtained by copolymerizing a cyclopentadiene-type monomer and a hydroxyl-containing monolefinic monomer at elevated temperatures, (b) a polyol selected from the group consisting of epoxy resins containing at least two hydroxyl groups in the molecule and epoxy resin derivatives containing at least two hydroxyl groups in the molecule and obtained by the reaction of epoxy resins with alkanolamines, and (c) an isocyanate-type curing agent. The compositions have improved low temperature curability, acid resistance and water resistance while retaining the various desirable properties of epoxy resins such as chemical resistance and oil resistance, and which when used as paints, exhibit improved adhesion to an adherend and improved re-coating adhesion to the film formed thereon.

摘要： A process for preparing a substantially gel-free thermoplastic resin having a softening point of 50.degree.-180.degree.C., an iodine value not exceeding 180 and a Gardner color of not more than 5 by heating at a temperature of 250.degree.-300.degree.C. a solution of a monomeric mixture consisting of 90-65% by weight of a cyclopentadiene type monomer and 10-40% by weight of a chain conjugated diolefin monomer of 4-5 carbon atoms at a monomer concentration of 70-95% by weight in a hydrocarbon solvent inert to thermal polymerization conditions to effect the thermal polymerization of the monomeric mixture and thereafter recovering the resulting polymer from the solvent.
