Molecular Weight Distribution in Emulsion Polymerization

A new Monte Carlo simulation model for the kinetics of emulsion polymerization is proposed. Normally, for emulsion polymerizations, each polymer particle consists of less than 10 8 monomeric units; therefore, the kinetic behavior of all polymer molecules in each polymer particle can be simulated easily using the Monte Carlo method with a well-designed algorithm. In the Monte Carlo technique, it is straightforward to account for virtually any kinetic event, such as the desorption of oligomeric radicals and chain length dependence of kinetic parameters, and as a consequence very detailed information such as the full distributions of the dead polymer molecular weights and macroradicals among polymer particles can be obtained
