Abstract

Monodisperse poly(D,L-lactide) (PDLLA) microspheres were prepared by dispersion polymerization of D,L-lactide in xylene/heptane (1/2, vlv) with poly[(dodecyl methacrylate)-co-(2-hydroxyethyl methacrylate)] (P(DMA-co-HEMA)) as a dispersion stabilizer. P(DMA-co-HEMA) contains hydroxy groups, which act as an initiation group for pseudoanionic dispersion polymerization. The best coefficient of variation (CV) values concerning particle diameter distribution and the particle diameter of obtained PDLLA microspheres were 3.7% and 5.3 μm, respectively. The particle diameter decreased with increasing concentration of P(DMA-co-HEMA) and HEMA maintained low CV (
