Method for synthesizing environment-responsive polymer through copolymerization modification of alkenyl sulfonate monomer
The invention relates to a method for synthesizing an environment-responsive polymer through copolymerization modification of an alkenyl sulfonate monomer. According to the invention, a hydrophobic monomer, an alkenyl sulfonate monomer and the like are used as main reaction raw materials, and the electric field response polymer is synthesized by a method comprising the steps of graft polymerization, cross-linking copolymerization modification and composite assembly. The hydrophobic monomer is subjected to graft polymerization and then cross-linking copolymerization modification is carried outon the alkenyl sulfonate monomer and a ligand under the action of a cross-linking agent to obtain hydrogel, and finally, composite assembly is carried out to obtain the electric field response polymer. On the basis of the application requirements of concrete material shrinkage reduction and crack resistance, the electric field response polymer is successfully synthesized in a mode of coating the branch structure polymer with the alkenyl sulfonate copolymerization modified hydrogel, the reaction process is energy-saving and efficient, the excellent composite effect of environmental response andconcrete shrinkage inhibition is shown. Wide market prospects and popularization and application potentials are realized.
