Poly(methyl methacrylate) (PMMA) particles were produced through dispersion polymerization using poly(styrene)-block-poly(4-vinylpyridine) block copolymer as a steric stabilizer in methanol. Lowmolecular-weight-distribution block copolymers were synthesized using 4-toluic acid dithiobenzoate through a reversible addition-fragmentation chain transfer (RAFT) method. Stable polymer particles were obtained when the block copolymer concentration was 1, 4, or 10 wt% relative to monomer. The average particle size (2.4 3.4 μm) varied depending on the concentration of the block copolymer. As the block copolymer concentration increased, the size of the particles decreased. In particular, 4 wt% of the block copolymer produced 2.7 μm monodisperse PMMA (Cv = 3.3 %). The existence of the block copolymer on the PMMA surface was verified through XPS measurements.
