【摘要】 以Ｎ，Ｎ’－亚甲基双丙烯酰胺为交联剂，采用溶液聚合法合成丙烯酰胺／Ｎ－乙烯基吡咯烷酮共聚物水凝胶．研究了合成条件对水凝胶溶胀度和凝胶强度的影响，并用该水凝胶来浓缩蛋白质稀溶液．更多还原

【Abstract】 in this paper, hydrogels of acrylamide (AM ) and N - vinyl pyrrolidone(NVP) copolymer were synthesized by solution polymerization, with N, N’ -methylene- his -acrylamide used as cross-linking agent. The effects of polymerization conditionson the swelling ratio and on the gel intensity of the hydrogels were studied. Also,the hydrogel was used to concentratie solution of protein.更多还原
