A series of polyphosphazenes with molecular brush type structures have been prepared with controlled molecular weights and narrow polydispersities. The polymers show lower critical solution temperatures (LCST) between 18 and 90 °C, which can be easily tailored by choice of side-substituent to suit the required application. A temperature triggered self-assembly is observed to give stable colloidal aggregates with dimensions in the region of 100-300 nm.
一系列具有分子刷型结构的聚磷腈已被制备出来，其分子量可控且多分散性窄。这些聚合物的低临界溶液温度（LCST）在18至90℃之间，通过选择侧链取代基可以很容易地进行调整以适应所需的应用。观察到温度触发的自组装会产生尺寸在100 - 300nm范围内的稳定胶体聚集体。
