Abstract: Polymerization of vinyl chloride in aqueous suspension in the presence of free-radical initiators of short half-life at pH's below 8. The temperature of the reactor wall must not be more than 20.degree.C above the temperature of the polymerization mixture during the heat-up phase and it must be lower than the temperature of the polymerization mixture during the subsequent polymerization phase. This procedure suppresses the formation of incrustations in the reactor.
