海藻酸钠-乙酸乙烯酯均相接枝共聚物合成及性能评价

摘要

Sodium alginate was hydrophobically modified with vinyl acetate by homogeneous graft copolymerization method .The graft yield,solubility and molecular weight of copolymer product (SA-g-PVAc)were evaluated with FTIR,elemental analysis and GPC, which also demonstrated performance changes with synthetic condition.%本文采用了均相接枝共聚的方法合成了疏水改性的海藻酸钠-乙酸乙烯酯共聚物（ SA-g-PVAc ）。使用红外光谱、元素分析、凝胶渗透色谱手段对产物接枝度、溶解性能、分子量进行了评价，并考察了相关性能的变化规律。
