wood products impregnated with from 30 to 80 % of a polymerizable monomer selected from the group consisting of hexanediol diacrylate and hexanediol dimethacrylate have excellent indent resistance . the wood products are impregnated with the monomer solution by placing the wood under a vacuum to remove air , contacting the wood with a monomer solution containing a polymerizable hexanediol diacrylate and / or hexanediol dimethacrylate monomer and from 0 . 5 to about 2 percent of a thermally activated free radical source as a polymerization initiator for a period sufficient to achieve the desired polymer loading . the wood is then heated under pressure to polymerize or cure the monomers .
