NIPAAm is a monomer which can synthesize intelligent polymers sensitive to environment. The method of synthesizing isopropylacrylamide is improved. The synthesis is noted for its simplicity, low toxicity, high yield and reproduction as compared with other methods. The melt point, boiling point, IR and NMR spectra of the compound were determined and compared with standard data and spectra for characterization. Further,linear p(NIPAAm) and p(NIPAAm) hydrogel were synthesized by using the NIPAAm and their temperature-sensitivity were investigated.
