Heterogeneous emulsion graft polymerization of glycidyl methacrylate on a wood matrix

The studies allowed developing an accessible method of synthesis of a highly permeable α-oxide copolymer of wood by emulsion graft copolymerization with the reactive monomer glycidyl methacrylate and establishing the optimum conditions for conducting the process. In modification of a natural polymer with GMA with a concentration of 10% for 60 min at 80 °C in the presence of the Fe²⁺—H₂O₂ initiating redox system with a 2.52 mg/g iron ion content of 0.017%, almost quantitative conversion of the monomer and a high degree of grafting efficacy was attained. The mass fraction of PGMA in the fibre phase is 88–90% and the EN is 19–21%. Translated from Khimicheskie Volokna, No. 5, pp. 18–22, September–October, 2008.
