The utility model discloses a PVC polymerization reaction temperature control system which comprises a polymerization kettle, a first temperature sensor and a second temperature sensor are respectively arranged in the polymerization kettle, a probe of the first temperature sensor is located on the center line of the polymerization kettle, and a probe of the second temperature sensor is located on the side wall of the polymerization kettle. The first temperature sensor and the second temperature sensor are arranged at the same height; a first flow regulating valve and a second flow regulating valve are respectively arranged on the first water inlet pipe and the second water inlet pipe; the device has the advantages that the amount of cooling water entering the heat exchange jacket, the inner cooling pipe and the kettle top condenser can be independently adjusted, so that the distribution uniformity of a temperature field in the kettle can be improved, the fluctuation of the kettle temperature is reduced, the u
