AMA-m-P(AA-co-NVP)共聚物水凝胶的合成与溶胀性能研究

摘要

合成了金刚烷胺改性丙烯酸-N-乙烯基吡咯烷酮(AMA-m-P(AA-co-NVP))共聚物水凝胶,通过改变原料配比可有效调控水凝胶的溶胀率.金刚烷胺(AMA)的比例越大,反应中和效率越低.随着反应物中AMA/AA和NVP/AA比例的升高,共聚物水凝胶的溶胀率逐渐增大.产物AMA-m-P(AA-co-NVP)聚合物水凝胶最大吸水率为312g/g.%N-vinylpyrrolidone-acrylic acid copolymer hydrogel modified by amantadine (AMA-m-P (AA-coNVP) ) has been prepared. The swelling rate could be effectively adjusted by changing the reactants ratio. In the synthesis experiment, neutralization efficiency decreased with increasing the amantadine content. With the increasing of AMA/AA and NVP/AA proportion, the swelling rate of the eopolymer hydrogel is ascendant. The maximum ratio for absorbing water of the copolymer hydrogel is 312 g/g.
