Abstract

Thermo-sensitive water-soluble copolymers based on N-isopropylacrylamide (NIPAAm) and methacrylic acid (MАAc) synthesized by solution polymerization technique with different monomer ratios and azo-bis-isobutyronitrile as an initiator. In order to characterize this synthesized copolymer, an analysis was carried out using various modern research methods. The structure, composition of water-soluble copolymers and homopolymer were studied by FTIR. The thermal properties of the thermosensitive copolymer were studied by thermogravimetric analysis (TGA) and differential scanning colorimetric (DSC) methods. In the thermogravimetric analysis, it was found that the mass loss of the copolymer occurs in two stages and the maximum decomposition temperature (PDTmax). The glass temperature of the NIPAAm-MAK copolymer was determined by the DSC method. The surface morphology of copolymer was analyzed using an optical microscope.
