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.
