Two novel monomers were synthesized by molecular design and their molecular structures were characterized by nuclear magnetic resonance (NMR). The effects of various solvents and initiator concentrations on the polymerization reaction were investigated. The effects of polymerization The relative molecular mass distribution of the polymer.According to the characterization of the polymer aqueous solution, it is confirmed that the obtained polymer has a high sensitivity to temperature change and is a novel thermosensitive material.
