Abstract
PURPOSE: To obtain in high yields, an oligomer having excellent compatibility with high-molecular materials such as rubber, by polymerizing under heat, di- or monomaleate or fumarate of dihydrodicyclopentadiene with maleic anhydride or a maleate ester.
CONSTITUTION: Mono(dihydrodicyclopentadienyl) maleate or fumarate, di(dihydro dicyclopentadienyl) maleate or fumarate and, if necessary, maleic anhydride or a maleic acid derivative are polymerized with heating, at 220W300°C, in the absence of a catalyst. The compounds used in the above reaction are represented respectively by formulas IWIV, wherein R1 and R2 are each H or alkyl. The oligomer thus produced has excellent compatibility and solubility in organic solvents, and is suitable as an additive for high-polar rubber such as nitrile rubber, paints, printing inks, pressure-sensitive adhesives, etc. Polymerization in the absence of a catalyst can offer a composition without gel formation with consequent improved yields.
