Poly(N-alkylacrylamide)s, Poloxamers, Poly(N-vinylcaprolactam)s, Chitosan, poly (ethylene oxide)- poly (propyleneoxide)- poly (ethylene oxide), Cellulose, xyloglucan, etc. are instances of thermally sensitive polymers (lactic acid) – tri blocks of poly (ethylene glycol). Poly (N-isopropyl acrylamide) and Poly (N-alkyl substituted acrylamides) with an annealing temperature of 32° C as well as poly (Nvinylalkylamides) like poly (N-vinyliso-butyramide) with just an annealing temperature of 39° C are perhaps the most extensively utilized thermally sensitive polymers [7, 35].
