The kinetics of methylmethacrylate radical polymerization in a continuous phase semi-batch polymerization reactor is studied.In the reactor

monomer and initiator are fed at a constant

small rate into a fixed amount of solvent.This type of reactor is useful in the production of a low molecular weight polymer which can be used to make coating and adhesive formulations.The kinetics model incorporates the rate of monomer consumption due to the reaction of Primary radicals with monomer

the rate of PMMA depolymerization at high temperature and the termination rate constant dependent on the gel effect.The model constants are regressed with the help of experimental data.
