Copolymers of acrylamide (AAm) and hydrophobic monomers are known as non-ionic polymers to show an upper critical solution temperature (UCST) in aqueous solution. By utilizing cyclic ketene acetals and carrying out the radical ring opening polymerization along with copolymerization with AAm, a UCST polymer, poly(acrylamide-co-2-methylene-1,3-dioxepane) (P(AAm-co-MDO)), is obtained. The AAm/MDO content results in the shift of UCST phase transition temperature. The present work shows how the combination of water-soluble PAAm and polycaprolactone-like structured PMDO develops a new type of thermoresponsive polymer which can be expected for bio-related applications.
丙烯酰胺（AAm）与疏水单体的共聚物被称为非离子聚合物，在水溶液中表现出上临界溶液温度（UCST）。通过利用环状烯酮缩醛并进行自由基开环聚合以及与AAm共聚，得到了一种UCST聚合物，即聚（丙烯酰胺-co-2-亚甲基-1,3-二氧六环）（P（AAm-co-MDO））。AAm/MDO的含量导致UCST相变温度的变化。目前的工作展示了水溶性PAAm和聚己内酯结构的PMDO的组合如何开发出一种新型的热响应聚合物，有望用于生物相关应用。
