Abstract
The invention relates to a method for preparation of a polymer from monomers comprising polyvinylidene fluoride, trifluoroethylene and a third monomer, the method successively comprising: injection of all the monomers to react into a reactor; initiation of a polymerization of the monomers; a continuation step (a) of the polymerization of the monomers, during which a drop in pressure in the reactor is compensated.
