Abstract. Emulsion polymerization involves the propagation reaction of free radicals with monomer molecules in a very large number of discrete polymer particles (10 16 –10 18 dm −3) dispersed in the continuous aqueous phase. The nucleation and growth of latex particles control the colloidal and physical properties of latex products.

small batch reactor, 100 ml of emulsion were used, and auxiliary equipment was designed to permit the reactor to be operated as a calorimeter to obtain polymerization rate data. The molecular weights of PVC polymerized in the reactor using a standard emulsion recipe appeared to be constant throughout the reaction up to a conversion of about 50%.
