摘要
研究了pH值敏感聚丙烯酸水凝胶的合成工艺及敏感性.详细研究了单体、摩尔比、引发剂用量、聚合温度、交联剂用量对温度及pH敏感聚(丙烯酸)-CO-(丙烯酰胺)水凝胶的收率及敏感性的影响.交联剂用量对溶胀比影响最显著,引发剂用量对收率影响最大.
The preparation and behavior of pH-sensitive polyarcylic and temperature-sensitive polyacrylamide are studied.The yield and pH-sensitive poly(arcylic)-co-(acrylamide) hydrogels are influenced by the molecular ration of acrylic and acrylamie,activator,polymerization temperature and cross link agent.The cross link agent is the most important factor for swelling ratio.The activator is the most important factor for yield.
