More Information
Summary:The invention relates to aqueous dispersions of fluoropolymers comprising recurring units derived from vinylidene fluoride (VDF) in an amount of from 60% to 82% in moles and recurring units derived from trifluoroethylene (TrFE) in an amount of from 18% to 40% in moles, with respect to the total moles of recurring units, said fluoropolymers possessing an improved thermodynamic ordered structure in the ferroelectric phase.
