Abstract
Abstract A wood-polymer composite is prepared by impregnating a wood substrate with a liquid dicyclopentenyl acrylate or methacrylate monomer of the formula <IMAGE> wherein R is hydrogen or methyl, R' and each R'' are independently hydrogen, chloride or bromide, n is 0 or 1, and the dashed line is an optional chemical bond with the provisoes that when the dashed line is present, n is 0, and when the dashed line is absent, n is 1, and curing the resulting monomer-impregnated wood substrate by either heating same in the presence of a catalytic amount of a thermal initiator, such as a peroxide, or by exposing same to high-energy radiation, such as gamma -rays. The wood-polymer composite is relatively hard and shows good resistance to hydrocarbon attack.
