基于聚乙烯醇的聚电解质渗透汽化膜的研究(Ⅰ)聚电解质的合成

摘要

以聚乙烯醇为基材合成了不同取代度的阳离子聚乙烯醇和磷酸酯化阴离子聚乙烯醇，初步研究了反应条件对取代度的影响.采用这两种材料制备了聚电解质复合物，并研究了这种复合物在水中的溶解性.%Based on poly(vinyl alcohol), phosphatic PVA and cationic PVAwith different substitution degrees were synthesized. Effects of synthesis conditions on substitution degrees were studied. With these two kinds of materials, polyelectrolyte complexes were formed and their aqueous solubilities were studied.
