摘　　要：在甲基丙烯酸N,N-二甲胺基乙酯(DMA)的乳液聚合体系中,加入不同比例的聚乙烯醇(PVA)得到了一系列PDMA/PVA复合薄膜,研究薄膜的热稳定性、透湿性及与沙林毒气模拟剂氯磷酸二乙酯(DCP)的作用效果.结果表明,随着PVA质量分数的增加,薄膜的透湿性能先增强后减弱,当PVA含量为30%时,薄膜的透湿性能达到最佳;而且,PVA含量增加使复合薄膜降解DCP性能降低.A series of PDMA/PVA polymers with different compositions were synthesized through emulsion polymerization and charactersized by thermal behaviors,water vapor permeability and degradating diethyl chlorophosphate（DCP）.The water vapor permeability of these PDMA/PVA polymers increases first and then decreases with the increasing of content of PVA.PVA-30 membrane shows the highest permeation in the as-synthesized polymers.Moreover,the results of DCP degradation for these membranes indicate that the content of PVA in the resulting polymers has slight effect on the degradation ability.
