Abstract

The emulsion polymerization kinetics of cyclohexyl methacrylate (CHMA) at 50°C using a mixture of anionic and nonionic surfactants was investigated. The product of the propagation rate constant (K~p~) and the number of radicals per particle (n̄) increased monotonously with the volume‐average particle diameter (D~v~). The value of K~p~ was estimated to be 260 L/(mol · s). Changing the monomer mass fraction in the recipe (from 0,14 to 0,40), the value of n̄ remained constant and close to 0,5. On the other hand, increasing the initiator concentration ([I]), the value of n̄ increased rapidly and then leveled off.
