Process for preparing tetrafluoroethylene copolymers with other perfluorinated monomers |
| abstract |
The invention relates to a process for obtaining copolymers of tetrafluoroethylene with one or more perfluorinated monomers having ethylenic unsaturation, said copolymers having only carboxylic or carboxylate groups as unstable end groups, by polymerization in aqueous emulsion in the presence of a dispersing agent. The process is characterized in that CHF2-CH3 is used as chain transfer agent, and an inorganic peroxidic compound is used as initiator. The carboxylic or carboxylate groups are successively transformed into stable groups of the -CF2H type by known stabilizing treatments. |
