TL;DR: In this article, the authors proposed a high polymer substrate having improved water and oil repellency, nonblocking properties, low coefficient of friction, bio-adaptability, chemical resistance, and transparency, comprising a discharge graft (co) polymer layer of fluorine-contaning unsaturated monomer on the surface.
Abstract: PURPOSE: A high polymer substrate having improved water and oil repellency, non-blocking properties, low coefficient of friction, bio-adaptability, chemical resistance, and transparency, comprising a discharge graft (co) polymer layer of fluorine-contaning unsaturated monomer on the surface. CONSTITUTION: A layer of a discharge graft (co) polymer consisting of a fluorine- containing unsaturated monomer is formed on the surface of a high polymer substrate, e.g. polythylene, regenerated cellulose, polyvinyl chloride, polyester, polycarbonate, etc, in the form of a block, plate ro film. The substrate is exposed to high-voltage discharge in an active or inactive gas to form active sites on the surface, which are brought into contact with a fluorine-containing unsaturated monomer, e.g. a methyl methacrylate derivative, etc., thus forming a graft (co) polymer layer on the surface COPYRIGHT: (C)1979,JPO&Japio

TL;DR: An epoxy resin composition consisting of a cyclopentadiene-type hydrocarbon resin having a hydroxyl value of 100 to 300 obtained by copolymerizing an epoxy resins with alkanolamines, and an isocyanate-type curing agent is presented in this article.
Abstract: 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.
