Molecular Weight Distributions of Polymer Formed in Emulsion Polymerizations
A theory for the molecular weight distributions (MEDs) of linear polymers made by emulsion polymerization is presented. Full account is taken of bimolecular termination, of exit from the part icles and of chain transfer. Analytic solutions are obtained for the full MWD, which are accurate if the average number of free radicals per latex particles is less than 0.7. Compartmentalistation of free radicals broadens the MWD and may change the shape of the MWD significantly.
