摘要
利用二异氰酸酯（ＴＤＩ和ＨＤＩ）与聚乙烯醇固化反应的产物不溶性判断该反应进程。研究反应温度、反应物配比等对反应的影响。研究表明，少量一二异氰酸酯的加入，较大程度地提高聚乙烯醇胶水的耐水性能。
The degree of the curing reaction was determined on the basis of the water-resistance of the products,by the reaction of Diisocyanate(TDI or HDI) with polyvinyl alcohol in aqueous solution.The in fluence of several reaction conditions were also discussed here.It was found a small amount of TDI or HDI will greatly improve the water-resistance of PVA film.
