Abstract

Resin impregnated wood is obtained using an impregnant composed of a monomer (I) which swells ligno-cellulose material or a mixture of (I) and a second monomer or prepolymer; and the product is irradiated. (I) contains one or more organic nitrogen functions e.g. amine, amide, nitrile etc. Examples of (I) are vinyl pyridine, acrylamide, acrylonitrile, N vinyl carbazole. In spite of its low resin content the wood is dimensionally stable, and maintains its light wt. and is hard. Solvent is not required for the impregnation and costly drying processes are avoided. The process can also be used to make high resin content, denser products.
