Patent ID: 7786228

Claim:
An optimization method in a polymerization system in which polymerization is carried out by the introduction of an initiator and heat is generated during the polymerization, wherein the optimization method comprises the steps of: (a) measuring the heat generation amount based on the composition of the initiator in the polymerization system to previously set the relationship between the initiator composition and the heat generation amount; (b) measuring the heat removal amount based on the temperature of a coolant in a cooling system of the polymerization system to previously set the relationship between the coolant temperature and the heat removal amount; (c) calculating the initiator composition allowable at a predetermined coolant temperature based on the relationships of Step (a) and Step (b) to previously set the relationship between the coolant temperature and the initiator composition; and (d) measuring the temperature of the coolant before and/or during the polymerization to adjust the composition of the initiator added at the measured temperature to the optimum condition, thereby decreasing the reaction time, and therefore, improving the productivity.
