有机两性共聚高分子互穿网络凝胶的制备方法
摘要：
本发明涉及一种有机两性共聚高分子互穿网络凝胶的制备方法。该方法是用甲基丙烯酰氧乙基三甲基氯化铵、甲基丙烯酸羟乙酯、富马酸作共聚单体，二甲基丙烯酸聚乙二醇酯作交联剂，过硫酸钾‑亚硫酸氢钠作引发剂在去离子水中进行共聚合反应得到有机两性共聚高分子第一网络凝胶；该第一网络凝胶在巴豆酸、木糖醇、甲基丙烯酸‑2‑乙基己酯、二甲基丙烯酸‑1,3‑丁二醇酯和去离子水配制的水溶液中溶胀，该水溶液中的单体、交联剂经过硫酸钾、吡哆醇盐酸盐的作用发生共聚合、酯化反应，最后得到有机两性共聚高分子互穿网络凝胶。
摘要（英）：

The invention relates to a preparation method of organic amphoteric copolymer interpenetrating network hydro-gel. The method comprises the steps of adopting methylacryloyloxyethyl trimethyl ammonium chloride, hydroxyethyl methylacrylate and fumaric acid as copolymerizable monomers, adopting dimethyl acrylate polyethylene glycol ester as a cross-linking agent, adopting potassium peroxodisulfate-sodium hydrogen sulfite as an initiator, and carrying out copolymerization reaction in deionized water to obtain organic amphoteric copolymer first network hydro-gel; swelling the first network hydro-gel in a water solution prepared from crotonic acid, xylitol, 2-ethylhexyl methacrylate, dimethacrylate-1,3-butanediol ester and deionized water, carrying out copolymerization and esterification reaction on a monomer and a cross-linking agent in the water solution through the action of potassium sulphate and pyridoxine hydrochloride, and finally obtaining the organic amphoteric copolymer interpenetrating network hydro-gel.
