| 摘 要： | 综述了温度敏感聚合物及其水凝胶最近几年的研究进展，讨论了该聚合物的组成、主链结构、分子量以及聚合方法对水凝胶和温敏聚合物的影响。随着聚合物的主链结构和侧链分子量的改变，聚合物的低临界溶解温度（LCST）可以在较宽的范围内进行调节。同时，活性聚合方法和普通自由基聚合方法也对水凝胶的相转变有着重要的影响。

| Abstract: | Thermoresponsive copolymers and hydrogels based on poly ethylene oxide （PEO） were reviewed in the article. The influence of the type of the main chain, the composition of the copolymers, the polymerization method and the degree of polymerization of the PEO on the thrmoresponsive coplymer and hydrogels were discussed. The LCST of the polymer decreases with the hydrophobic properties of main chain. And two polymerization methods were used and polymerization technique strongly influenced the phase transition of the hydrogels. |
