Abstract

The invention provides a synthetic method of ionic liquid polymer containing imidazole in main chain, comprising imidazole respectively reacting with 2-chlorohydrin and methyl chloroacetate to synthesize chloridized 1,3- bi(2-hydroxyethyl)imidazole ionic liquid and chloridized 1,3- bi(2-methoxy-2-oxyethyl)imidazole ionic liquid; the two ionic liquid being used as monomer to perform melt phase polycondensation in the present of catalyst SnCl2. The ionic liquid polymer has good conductivity property (conductivity: 5.4-7.2*10-5S / m.). Because the ionic liquid unit is induced, the new type polymer has application future in polyelectrolyte, gas separation film and so on.
