敏感型：在所有链末端具有N-异丙基酰胺（NIPAM）基团的树枝状聚合物和聚（N-异丙基丙烯酰胺）（PNIPAAm;见图）中观察到较低的临界溶解温度（LCST）。对于NIPAM封端的树枝状聚合物，在LCST附近出现小得多的吸热峰。树枝状聚合物的球形结构可能分别在低于和高于LCST的NIPAM基团周围引起低效的水合和脱水。
(Graph Presented) The sensitive type: A lower critical solution temperature (LCST) is observed for dendrimers with N-isopropylamide (NIPAM) groups at all chain terminals and for poly (N-isopropylacrylamide)(PNIPAAm; see picture). A much smaller endothermic peak occurs around the LCST for NIPAM-terminated dendrimers. The globular structure of the dendrimers may cause inefficient hydration and dehydration around NIPAM groups below and above the LCST, respectively.© 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
