  • Method of manufacturing vinylidene difluoride and trifluoroethylene-based dielectric copolymers
    Patent number: 7750098
    Abstract: A method of manufacturing, by suspension polymerization, dielectric copolymers, including injecting an initial mixture of constituent monomers into an autoclave at constant temperature and pressure, wherein the mixture of constituent monomers including vinylidene difluoride (VDF), trifluoroethylene (TrFE), and a monomer 2 to 10 times more reactive than VDF and TrFE; and continuously reinjecting at constant pressure, as soon as the reaction is initiated and throughout the duration of polymerization, a second mixture of the constituent monomers, wherein the molar composition of the initial mixture and the second mixture are determined by calculation, in a manner known of itself, taking into account the desired molar composition of the copolymer and the higher reactivity of the third monomer.
    Type: Grant
