Dispersion copolymerizations of styrene (St) and methyl acrylate (MA) (100/0~0/100 wt%) in isopropanol/water media were carried out. The poly(St/MA) latexes, containing 100/0~50/50 wt%, had a narrow size distribution in the size range of 1.3~2.0 μm. The particle size of the poly(St/MA) latexes increased, and the molecular weight of the latex polymers decreased, upon increasing the MA content. Dispersino copolymerization of St/MA (75/25 in wt%) was also carried out to investigate the effects of various polymer ization parameters on the particle size and the molecular weight of the resulting poly(St/MA) latexes. The number-average particle diameter increased upon increasing the reaction temperature and the concentrations of the monomer and ALBN initiator, and upon decreasing the concentratino of PVP stabilizer and the water content in the isopropanol/H2O media. The weight-average molecular weight increased upno increasing the concentrations of monomer and steric stabilizer and the water content in the isopropanol/H2O media, but it decreased with the initiator concentration and polymerization temeprature. The preferred polymerization recipes for makning uniform poly(styrene-co-methylacrylate, 75/25 wt%)microparticles in size range 1.3~3.4 μm is established.
