    • A polyamine adduct including the reaction product of (a) a divinylarene dioxide, and (b) an excess of a polyamine to provide an adducted polyamine composition; a process for making the adduct; a curable epoxy resin composition including (i) the adduct derived from divinylbenzene such as divinylbenzene dioxide (DVBDO), (ii) at least one epoxy resin, and (iii) optionally, a co-curing agent and/or a catalyst; and a cured product made from said curable epoxy resin composition. The cured product made from the curable epoxy resin composition is thermally stable and offers improved properties such as a low viscosity and a high heat resistance.

    • The present invention is directed to the preparation of a self-curing curable epoxy resin composition comprising the reaction product of an epoxy resin starting material containing an initial concentration of cyclic dimer and a sufficient amount of a cyclic anhydride to reduce the concentration of cyclic dimer in the resulting epoxy resin reaction product to a level 50 % or greater than that of the epoxy resin starting material. The compositions of the present invention are cyclic anhydride grafted epoxy resins bearing terminal epoxy groups and having been reacted with sufficient amounts of cyclic anhydride to significantly reduce the concentration of cyclic dimer without causing crosslinking or gelling. These cyclic anhydride grafted epoxy resins form coatings having excellent properties and are useful in various applications including can and coil coatings.
    • 本发明涉及一种自固化型固化性环氧树脂组合物的制备方法,该组合物包含含有初始浓度的环状二聚体的环氧树脂原料与足够量的环状酸酐的反应产物,以降低环状二聚体的浓度 所得到的环氧树脂反应产物达到环氧树脂起始原料的50%以上的水平。 本发明的组合物是具有末端环氧基团的环状酸酐接枝的环氧树脂,并且已经与足够量的环状酸酐反应,以显着降低环状二聚体的浓度,而不引起交联或胶凝。 这些环状酸酐接枝的环氧树脂形成具有优异性能的涂层,并且可用于包括罐和卷材涂层在内的各种应用中。
