A thermoresponsive polyester comprising units derived from an amide functional diol compound having a first amide group having a nitrogen atom and a carbonyl group; a second amide group tethered directly or indirectly through an organic group at the carbonyl group of the first amide group; and two organic groups terminated with a hydroxyl group attached to the nitrogen atom of the first amide group. The thermoresponsive polyesters exhibit a lower critical solution temperature at which they undergo a thermally induced reversible hydrophobicity change. This hydrophobicity change may involve the formation of coacervates of the thermoresponsive polyesters which can then coalesce into a precipitated polymer rich phase.
一种热响应性聚酯,包括由含有第一个酰胺基团(具有氮原子和羰基)的酰胺官能二元醇化合物单元构成;第二个酰胺基团通过有机基直接或间接地连接到第一个酰胺基团的羰基上;以及两个有机基终止,带有羟基连接到第一个酰胺基团的氮原子上。这种热响应性聚酯在低临界溶液温度下表现出热诱导可逆疏水性变化。这种疏水性变化可能涉及形成热响应性聚酯的共聚物凝胶体,然后这些凝胶体可以凝聚成沉淀的富聚合物相。
