“…Interestingly, the LCST in this group of polymers varies according to the type of N-substituted groups, ranging from materials insoluble at room temperature to other with high LCST [65] . They include poly (N-isopropylacrylamide) [2,56,62,65,[73][74][75] , poly (N,N-diethylacrylamide) [2,56,59,62] , poly (2-carboxyisopropylacrylamide), poly (N-(L)-(1-hydroxymethyl) propylmethacrylamide, poly (N-acryloyl-N'-propilpiperazine) [2] , poly (N-ethylacrylamide), poly (N-methyl-N-ethylacrylamide), poly (N-n-propylacrylamide) [56,65] , poly (N-ethylmethacrylamide), , poly (N-cyclopropymethacrylamide) [56] , poly (N,N-bis(2methoxyethyl) acrylamide), poly (N-(3-methoxypropyl) acrylamide), poly (ethoxypropylacrylamide) [65] and poly (aminomethoxypropylacrylamide) [76] .…”
