Abstract
The invention provides a process for polymerizing at least one fluoromonomer in the presence of a cyclic perfluorinated amine. Perfluoro-N-methylmorpholine is a preferred cyclic amine.
Claims11
In the process for synthesizing a fluoropolymer, comprising polymerizing at least one fluoromonomer in a polymerization medium containing a non-aqueous liquid phase, the improvement comprising carrying out said polymerization in the presence of a perfluorinated cyclic tri-substituted amine having the nitrogen atom in the ring and no N--F bond, having at least four atoms in the ring, having a total of 3-12 carbon atoms, and optionally containing an additional hetero atom, substantially constituting said non-aqueous liquid phase.
