Poly(N‐isopropylacrylamide) is a thermosensitive polymer which undergoes coil to globule transition in which chains collapse and aggregate when passing to and above lower critical solution temperature (LCST). This property of the polymer is due to its unique structure. The synthesis of thermosensitive polymer Poly(N‐isopropylacrylamide) by novel and eco‐friendly routes has been reported in this work. The synthetic routes adapted are microwave method and a nonlinear chemical oscillator. In both of these methods, chemistry of polymerisation takes place in a single pot involving less toxic end products. To evolve a comparative trend conventional method was also used as a standard. Based on this, the mechanism for the synthesis of thermosensitive polymer was also proposed. It is found that the above mentioned nonconventional methods of synthesis have advantages over the conventional method in terms of the time of reaction and yield. The polymers synthesized by different routes were then characterised by different techniques which confirmed their thermosensitive behaviour and other properties.
