    摘要: 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.
