The multiple initiator method of controlling polymerization at a prescribed rate is studied. A correlation of the auto-acceleration function with the kind and concentration of the initiator is assumed. The equations for the determination of the kind and concentration of the initiator to control polymerization at a constant rate are then derived. Bulk polymerization of methyl methacrylate is chosen for verification. Using the method proposed and binary initiator systems, we determine several sets of initiator pairs and their concentrations for polymerization of methyl methacrylate at rates of 0.1 and 0.2 h-1 for various reaction temperatures. The results indicate that the polymerization rates obtained with the given initiator pairs and concentrations are what we have prescribed.
