Abstract
The polymerization of tetrafluoroethylene in aqueous suspension can be carried out with high conversion if the medium is thoroughly mixed using an axially conveying stirrer element in such a manner that a cone forms at least as far as the vicinity of the stirrer element. In the region of this stirrer element there are expediently arranged baffles which extend only over a part of the filling height of the reactor.
