## Abstract A sensitivity analysis is performed to determine at what conditions the simplified model for swelling of latex particles by two monomers or two solvents is valid. This model proposes that, inter alia, the fractions of two monomers in the latex particles and in the monomer droplets are e

โฆ Synopsis
Recently, we suggested a novel swelling method to make polymer seed particles absorb a large amount of monomer prior to the seeded polymerization for preparing monodispersed polymer particles having diameter above 5 pm, which we named the "dynamic swelling method." This article discusses the thermodynamic background of this method, both theoretically and experimentally.

For the purpose of extending the size range of polymer seed particles used in "dynamic swelling method" (DSM), first it was verified theoretically that the submicron-sized polymer particles produced by emulsion polymerization can also absorb a large amount of monomer by DSM in both equilibrium and k
The thermodynamic simulation under the kinetic control state indicates that 1.77-m-sized monodispersed polystyrene (PS) particles can absorb 500 times the amount of the styrene monomer with keeping the monodispersity by the "dynamic swelling method" (DSM) which the authors proposed in 1991. Actually
