Synthesis of unsaturated quaternary ammonium salts and application of their polymers in chemical engineering and environmental protection

Unsaturated quaternary ammonium salts are classified according to the types of unsaturated group and their synthesis methods are reviewed. The applications of the poly quaternary ammonium salts in oily-wastewater treatment,sterilization,textiles,new materials and other areas are introduced. The problems in synthesis of quaternary ammonium salts and application of their polymers are elaborated. The directions for further research are pointed out as followsinvestment in scientific research should be increased to speed up the development process of novel unsaturated quaternary ammonium salts,especially in main structure designing,purity increasing and monomer variety for new flocculant,in order to prepare multifunctional monomers and polymers.
