Abstract
The invention relates to a method for synthesizing 2,3,3,3-tetrafluoropropene containing fluoropolymers using non-fluorinated surfactants in an emulsion process. No fluorinated surfactants are used in the process, and a persulfate initiator is used as the primary initiator. The process produces high molecular weight copolymers.
