摘要
本文研究了高吸水性水解(丙烯酸甲酯-醋酸乙烯酯)共聚物-H(MA-VAC)的制备及性能。并通过氢核磁共振(H-NMR)、裂解气相色谱(PGC)、红外光谱(IR)、X-射线衍射(X-RD)、透射电镜(TEM)及相位差显微镜(PCM)等探讨了该共聚物的结构及吸水机理.结果表明,H(MA-VAC)树脂具有“海岛”型微相分离结构,PVA 微晶结构起交联点作用,其吸水能力主要是 PAANa 贡献.H(MA-VAC)是一种新型的、吸水能力高、抗盐性较好的高吸水性树脂。
A method of synthesizing hydrolyzed poly(methyl acrylate-vinyl acetate) was suggested.The structure of the copolymer was identified by H-NMR,IR, pyrolysis gas chromatography,X-ray diffraction,transmissive electronmicro- ssope and phase contract microscope,The copolymer is“island”like phase separated and is a super water-absorbent resin with high water-absorbability and goog resistance to salt.
