Abstract: The P(NIPAAm-co-AAPBA-co-HPM-co-TMSPM) quaternary copolymers were synthesized by free radical polymerization of N-isopropylacrylamide (NIPAAm),3-acrylamidophenylboronic acid (AAPBA), hydroxypropyl methacrylate (HPM) and 3-trimethoxysilylpropyl methacrylate (TMSPM). Fourier transform infrared (FTIR) spectrometry, nuclear magnetic resonance hydrogen (1H-NMR) spectroscopy and dynamic light scattering (DLS) technique were used to analyze and identify the chemical structure, molecular composition and responsive behaviors of the copolymers. The results indicated that the resultant copolymers with short chains, were composed of NIPAAm, AAPBA, HPM and TMSPM in the designed molar ratios of reactants, and they displayed excellent dual-response towards temperature and glucose.
