The particle growth in the graft free-radical copolymerization of styrene (St) and acrylonitrile (AN) in the presence of poly(propylene glycol) is investigated by experiments and modeling. The concentrations of chain transfer agent and macromer, and the St/AN ratio play important roles in particle size and its distribution. A particle size model is developed and an analytic expression for the particle size in terms of monomer mass concentration (Wmt0), initiator molar concentration ([I]0), and macromer mass concentration (WM0) is derived. The particle size is described experimentally as: . Particle growth processes under various experimental conditions are well described by the model.
