Resumo: This study aimed to demonstrate the feasibility of obtaining wood-polymer composites (WPC) displaying a performance superior to that of untreated wood from reforested genera. To this end, wood samples of Pine (Pinus caribaea) and Eucalyptus (Eucalyptus grandis), whose density is compatible with this process, were impregnated with the polymeric monomers styrene and methyl methacrylate, using benzoyl peroxide to initiate the polymerization process forming free radicals. The vacuum-pressure method was used to impregnate the samples with monomer-initiator solution. The results indicated a significant improvement of all the properties investigated, including dimensional stability, for the Pine-WPC, while Eucalyptus-WPC, owing to the wood's low permeability, showed only increased values of hardness parallel and perpendicular to grain.
