Abstract

PURPOSE: To prevent deposition of scales and thereby to obtain high-quality polymer particles, by carring out polymerization while injecting water containing a metal halide and an organic hydroxycarboxylic acid into a vinyl chloride monomer vapor rising into a reflux condenser.
CONSTITUTION: Vapors of a vinyl chloride monomer or the like is passed through a transfer conduit 3 to a reflux condenser 2, condensed therein and recirculated into a polymerization tank 1. From a water sparger 4 provided within the upper portion of the reflux condenser, water containing a metal halide such as CuCl and/or an organic hydroxycarboxylic acid (salt) such as citric acid is sparged uniformly to uniformly wet the inner surfaces of the condenser 2, and at the same time the water containing a metal halide and/or an organic hydroxycarboxylic acid (salt) is injected countercurrently through a water injection port 5 provided in the transfer conduit 3 between the polymerization tank 1 and the reflux condenser 2. The amount of water from the water injection ports 4 and 5 is 10W35%, pref. 15W25%, of the amount of water charged in the polymerization tank.
