Abstract

Wood preservation based on in situ polymerization of potentially bioactive monomers has been studied. Tributyltin oxide acrylate (TBTOA) and pentachlorophenol acrylate PCPA) were synthesized. Wood samples were treated at 2%, 5%, 10%, 15% and 20% by weight solutions with varying amounts of either crosslinker (trimethylolpropane trimethacrylate, TMPTM) or methyl methacrylate (MMA) and polymerized in situ in wood samples. Soil block testing was performed on acetone leached samples using Gloeophyllum trabeum in a standard ASTM test for 12 weeks. TBTOA was effective at all levels except when using greater than or equal to 10% crosslinker concentrations. PCPA showed some efficacy with 0% crosslinker present, but otherwise it gave no more protection than the MMA controls alone.
