Abstract

In the process, the vault of the reactor is kept, during the reaction, under a continuous flow of water at a pressure of >/= 15 kp/cm<2> and, after the reaction has taken place, the residual encrustations on the reactor vault are removed mechanically with high-pressure water at >/= 100 kp/cm<2>. As means for carrying out the process, a device comprising a hollow shaft (1) having nozzles (3) and having axial and rotary movement is used. The process is applied in polymerisations of vinyl chloride by itself or as a mixture with other monomers containing 20 % by weight or less of comonomer. <IMAGE> [GB1519359A]
