Beschreibung
Zusammenfassung:	The invention provides novel latexes of particles of vinylidene fluoride/trifluoroethylene copolymers possessing a more ordered ferroelectric crystalline phase, and hence improved ferro-, pyro-, and piezo-electric properties, and a method for manufacturing the same by emulsion polymerization in the presence of certain cyclic fluorosurfactants. L'invention concerne de nouveaux latex de particules de copolymères de fluorure de vinylidène/trifluoroéthylène possédant une phase cristalline ferroélectrique plus ordonnée, et, par conséquent, des propriétés ferro-, pyro- et piézo-électriques, et leur procédé de fabrication par polymérisation en émulsion en présence de certains tensioactifs fluorés cycliques.
