ABSTRACT:
This invention relates to a method for the preparation of aqueous dispersions of polytetrafluoroethylene comprising polymerizing tetrafluoroethylene in an aqueous medium containing a polymerization initiator and an appropriate emulsifying agent as well as other necessary additives in the presence of a stabilizing amount of a stabilizing agent selected to be a saturated halogenated acyclic or cyclic hydrocarbon containing less than about 20 carbon atoms or an unsaturated halogenated acyclic or cyclic hydrocarbon containing less than about 20 carbon atoms which is not copolymerizable with the tetrafluoroethylene under the reaction conditions, or a mixture of said halogenated hydrocarbons.
