The improvement of Brinell hardness of sugar maple ( Acer saccharum Marsh.) samples through impregnation and in‐situ polymerization of methyl methacrylate, 2‐hydroxylethyl methacrylate, and ethylene glycol dimethacrylate monomers was investigated. The formulation combinations were determined by a mixture design. Sugar maple samples were impregnated with these mixtures by a vacuum and pressure process and polymerized in situ by a catalyst‐thermal procedure. The effects of the monomers and their combinations on Brinell hardness and hardness modulus were analyzed. Chemical impregnation enhanced both Brinell hardness and hardness modulus. A significant relationship between hardness modulus and Brinell hardness was found. Modulus of elasticity of sugar maple was also improved through impregnation with methacrylates. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 99: 1674–1683, 2006
