摘要: 介绍聚乙烯醇中分子间、分子内氢键定义和表征方法 ,讨论了残留的羧基与聚乙烯醇的构象及结晶度对氢键形成的影响 ,分析了聚醋酸乙烯分步醇解纺丝和直接醇解纺丝中氢键的形成与结晶度。指出 :有效控制氢键形成是制备高强高模PVA纤维的关键。

Abstract: The characterization and definition of intermolecular and intramolecular hydrogen bonds in PVA (poly(vinyl alcohol))were introduced. The remaining actetate and conformation as well as crystallinity in PVA were considered to affect formation of hydrogen bonds.Hydrogen bonds and crystallinity in the techniuqes of gel spinning of partially saponificated PVA and of direct alcoholysis spinning of poly(vinyl acetate)were analysed.The result shows that controlling the formation of hydrogen bonds is the key in the preparation of high tenacity and high modulus PVA fibers.
