Wood Modification of Pinus densiflora Sieb. et Zucc. for korean traditional latticework by combined treatment of Acetylation followed by Styren-Methyl metacrylate impregnation

Wood cell-wall modification with acetic anhydride, lumen filled with styren monomer and methyl methacrylate, and a combination of these two treatments were studied for their effectiveness for dimensional stability. Compared to those of untreated Pinus densiflora Sieb. et Zucc. and sole acetylated red pine, The combination of acetylation and impregnation with methy methacrylate greatly reduced water absorption, increased ASE to the best and gave better bending strength and compression strength.
