The latex particles can maintain an appreciablestability during the emulsifier-free emulsion copolymerization of MMA and BA in thepresence of HEMA The average particle diameter increase with an increase of totalsolids content, HEMA content, PSP content, ioniC strength of the system and monomerfeed rate, and decrease with the monomer feed ratio From 3/1(MMA/BA;molar ratio.)to1/3. The stability of this reaction system is improved by adding HEMA as nonioniccomonomer High solids content (50%) latex with monodisperse particle can beobtained using this process.展开更多
