| Abstract: | The sendbatch emulsifier-free emulsion copolymerization of methyl methacrylate (MMA) and n-butyl acrylate (BA) in the presence of 2-hydroxyethyl methacrylate (HEMA) initiated by K2S2O8 (PSP) was studied. The average palticle diameter increases with an increase of total solids content, HEMA content, PSP content, ionic strength of the system and monomer feed rate, and decreases with the monomer feed ratio from 3/1 (MMA/BA mole.) to 1/3. The stability of this reaction system is improyed by adding HEMA as nonionic comonomer. The high so1ids content (50%) latex with monodisperse particle can be obtained using this process. |
