乙烯基磷化合物，如聚乙烯基膦酸（PVPA），聚二甲基乙烯基膦酸盐（PDMVP），与单一使用相比，通过组合使用聚硼酸钠（SPB），赋予木材与传统防火木材相当的高阻燃性。差热分析和热重分析（DTA/TG）表明SPB和PVPA之间存在协同效应。经SPB浸渍后，木材内部的二甲基乙烯基膦酸酯（DMVP）与甲基丙烯酸甲酯（MMA）共聚，提高了木材的耐水性，浸出试验后木材的不燃性基本保持不变。经DMVP和MMA处理的木材经SPB处理后的燃烧残留物显示出较高的抗压强度，其SEM图像表明强度是由形成的木炭引起的。
Vinyl phosphorus compounds such as poly (vinyl phosphonic acid) (PVPA), poly (dimethyl vinyl phosphonate) (PDMVP) impart high flame retardancy to wood comparable to conventional fireproofing wood by combined use of sodium polyborate (SPB) in contrast to their single use. The differential thermal analysis and thermogravimetry (DTA/TG) suggest a synergy effect between SPB and PVPA. The water resistance of the treated wood is improved by copolymerization of dimethyl vinyl phosphonate (DMVP) with methyl methacrylate (MMA) inside the wood after the impregnation of SPB, and the incombustibility of the wood is mostly maintained after leaching tests. The combustion residues of the wood treated with DMVP and MMA after SPB show high compressive strength, and their SEM images suggest that the strength is due to formed charcoal.
