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.

UCST型共聚物，是水溶性聚丙烯酰胺和类似聚己内酯的聚酯结合而成。

丙烯酰胺（AAm）和疏水性单体的共聚物被称为非离子聚合物，在水溶液中具有较高的临界溶液温度（UCST）。通过使用环状乙烯酮缩醛并进行自由基开环聚合以及与Aam的共聚，UCST聚合物聚（丙烯酰胺-co-2-亚甲基-1,3-二氧戊环）（P（AAm-co-MDO）），获得。AAm / MDO含量导致UCST相变温度的变化。目前的工作表明了水溶性PAAm和聚己内酯样结构化PMDO的结合如何开发出一种新型的热响应性聚合物，有望用于生物相关应用。
