最近的研究表明，含有疏水主链和短亲水低聚（乙二醇）侧链的合成聚合物在水介质中可能表现出较低的临界溶解温度（LCST）。特别是，用低聚（乙二醇）丙烯酸酯或甲基丙烯酸酯构建的聚合物似乎特别有前途。实际上，这些低聚（乙二醇）（大分子）单体通常是可商购的，并且可以通过可逆加成-断裂转移聚合（RAFT）或原子转移自由基聚合（ATRP）容易地聚合。后一种技术是非常通用的，并允许各种各样的刺激响应材料的合理设计。例如，在本章中，温敏水凝胶，聚合物胶束和平面基板的一些例子。
It was recently demonstrated that synthetic polymers containing a hydrophobic backbone and short hydrophilic oligo(ethylene glycol) side-chains may exhibit a lower critical solution temperature (LCST) in aqueous medium. In particular, polymers constructed with oligo(ethylene glycol) acrylates or methacrylates seem particularly promising. Indeed, these oligo(ethylene glycol) (macro)monomers are often commercially available and can be easily polymerized by reversible addition-fragmentation transfer polymerization (RAFT) or atom transfer radical polymerization (ATRP). The latter technique is very versatile and allows the rational design of a wide variety of stimuli-responsive materials. For example, in the present chapter, some examples of thermoresponsive hydrogels, polymeric micelles and planar substrates are presented.
