Summary: A novel thermosensitive amphiphilic copolymer of PNIPAm grafted polyphosphazene (PNIPAm‐g‐PPP) has been synthesized through a co‐substitution reaction of poly(dichlorophosphazene) with amino terminated NIPAm oligomer and glycine ethyl ester (GlyEt). The polymer obtained had a molar ratio of 1:5.25 PNIPAm to GlyEt and had a lower critical solution temperature (LCST) near 30 °C. The formation of polymeric micelles was confirmed by fluorescence, dynamic light scattering and transmission electron microscopy measurements.
The structure and formation of thermosensitive micelles of poly(N‐isopropylacrylamide) grafted polyphosphazenes synthesized here.
