    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.

    Abstract: A polymerization apparatus equipped with a circuit made up of a polymerization vessel, a heat exchanger placed outside said polymerization vessel, and a circulation pipeline extending from said polymerization vessel and returning to said polymerization vessel through said heat exchanger, a branch pipeline being connected to said circulation pipeline through a ball valve comprising a spherical valve element and a valve body for housing said spherical valve element, wherein the valve body of said ball valve is joined directly to said circulation pipeline, and a method of producing a polymer of a monomer having an ethylenically unsaturated double bond by using said apparatus. Scale and polymers in the form of blocks can be prevented from mixing with the reaction mixture. Therefore, where the obtained polymer is formed into a sheet or the like, the fish eyes can be decreased, and if the polymerization is repeated, clogging of the tubes of the heat exchanger and drop in the flow velocity of the reaction mixture can be prevented.
