ABSTRACT:
A method and an apparatus for removing the heat of polymerization evolved during a polymerization procedure carried out while the liquid polymerization mixture is stirred in a reactor are provided. A condensable vapor present in the space above the liquid level of the polymerization mixture inside the reactor is condensed by a cooling means provided in said space while the inner pressure of the reactor is maintained at a level such that the polymerization mixture does not boil. Preferably, the vapor phase is stirred.
