通过N-羟甲基丙烯酰胺与衣康酸、N-羟甲基丙烯酰胺与β-衣康酸氢甲酯的自由基共聚合制备了共聚物凝胶。两种单体的比例从25至75摩尔%变化，并研究了外部刺激如溶胀介质的pH和离子强度的影响。凝胶是pH响应性的，并且溶液的离子强度的增加引起共聚物凝胶的平衡溶胀度的降低。用Kelen-Tudos方法测定单体竞聚率。此外，共聚物的组成对两种共聚物的平衡溶胀行为有显着的影响。(c)2006 Wiley Periodicals，Inc.
Copolymer gels were prepared by the radical copolymerization of N-hydroxymethyl acrylamide with itaconic acid and N-hydroxymethyl acrylamide with beta-methyl hydrogen itaconate. The ratios of both monomers were varied from 25 to 75 mol %, and the effects of external stimuli such as the pH and ionic strength of the swelling media were investigated. The gels were pH-responsive, and an increase in the ionic strength of the solutions caused a decrease in the equilibrium degree of swelling of the copolymer gels. The monomer reactivity ratios were determined with the Kelen-Tudos method. Moreover, the copolymer composition had a significant effect on the equilibrium swelling behavior of the two copolymers investigated. (c) 2006 Wiley Periodicals, Inc.
