Emulsion Polymerization of 2-Hydroxyethyl Methacrylate
Abstract:
The effects of initiator system,emulsifier type and amount,reaction temperature,and electrolyte on monomer conversion,coagulum content,particle size and distribution for the emulsion polymerization of the water-soluble 2-hydroxyethyl methacrylate (HEMA) were investigated.The results showed the oil-soluble initiator azoisobutyronitrile (AIBN) may increase the monomer conversion and decrease the coagulum;the amount of the emulsifier had little effect on the monomer conversion,but the coagulum greatly decreased with the increase of the amount of the emulsifier.As the reaction temperature increased from 65℃ to 85℃,the monomer conversion increased first and then decreased,and the coagulum increased continuously,and the ideal reaction temperature was 75℃.The presence of electrolyte,NaHCO3,decreased the monomer conversion;the particle distribution index was broader and multimodal distributions were observed.
