Abstract
Disclosed herein is an optimization method in a polymerization system in which heat is generated during the polymerization with an initiator. The optimization method includes the steps of 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, 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, calculating the initiator composition allowable at a predetermined coolant temperature to previously set the relationship between the coolant temperature and the initiator composition, and 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.
