Abstract: The invention relates to a process for reducing the defectivity of a block copolymer (BCP1) film, the lower surface of which is in contact with a preneutralized surface (N) of a substrate (S) and the upper surface of which is covered by an upper surface neutralization layer (TC) in order to make it possible to obtain an orientation of the nanodomains of the block copolymer (BCP1) perpendicularly to the two lower and upper interfaces, where the upper surface neutralization layer (TC) employed to cover the upper surface of the block copolymer (BCP1) film comprises a second block copolymer (BCP2).

Abstract: The invention relates to a process for controlling the structure of a block copolymer by selective copolymerization, by ring opening, of cyclic carbonate and lactone monomers in the presence of a catalyst based on methanesulfonic acid, the said process comprising a sequence of stages carried out strictly in the following order: a) dissolving the cyclic carbonate monomer in a nonchlorinated aromatic solvent, b) adding, to the monomer solution, a bifunctional initiator chosen from diols or water, c) adding methanesulfonic acid (MSA) as catalyst of the polymerization reaction, d) when all the cyclic carbonate has been consumed, a telechelic polycarbonate capable of acting as macroinitiator of polymerization of the lactone is obtained, e) adding the lactone to the reaction medium in order to selectively obtain a block copolymer.

Abstract: The present invention relates generally to the field of the storage of electrical energy in all-solid-state batteries, in particular in storage batteries of Li-ion type. More specifically, the invention relates to a solid electrolyte consisting of a polymer matrix and of a fibrous reinforcement which makes possible the manufacture of a non-porous film exhibiting a very good compromise between ion conductivity, electrochemical stability, high-temperature stability and mechanical strength. This film is intended for an all-solid-state battery separator application, in particular for Li-ion batteries. The invention also relates to an all-solid-state battery comprising such a separator and/or such an electrolyte.

Abstract: The invention relates to a method for eliminating metal ions from a viscous organic solution, the viscosity of which at 20° C. is between 1 and 1000 cP. This method comprises the steps consisting in placing a macroporous ion-exchange resin in a column, said resin comprising at least one acid resin of carboxylic type, based on a copolymer having active groups in carboxylic form (CO2H), then in continuously passing said viscous organic solution over said ion-exchange resin.
