摘　　要：本文研究了经干热处理聚乙烯醇纤维的缩氯乙醛及缩苯甲醛化反应。发现阻溶胀剂硫酸钠浓度对聚乙烯醇纤维缩氯乙醛化的后期缩醛反应无明显影响,而氯化锌对聚乙烯醇纤维缩苯甲醛化反应有催化作用。The acetalization reactions of the heat-treated PVA fibres with chloroacetaldhyde and ben-zaldehydc have boon studied. It was discovered that there was no distinct effect of the concentration of sodium sulfate, an anti-swelling agent, on the aceta lizing degree during the later period of the acetalization of PVA fibres with chloroacetaldehyde. But the zinc chloride, an another anti-swelling agent, appears to have catalyzing action to the acetalization of PVA fibres with benzal-dehyde.
