Abstract
A method for preparing a copolymer of general formula (I) by electrochemically copolymerising a compound of general formula (II) with a compound [A], wherein [A] is a monomeric unit of a polymer capable of being produced by electrochemical copolymerisation, [B] is a side group that may be a monomer or a polymer and is bound to unit [A] by a covalent bond or via a spacer arm, and x and y are integers of a least 1. Said method includes a treatment enabling the surface reactivity of said copolymer to be reduced.
Claims7
Method for reducing the surface reactivity of a copolymer produced by electrochemical copolymerization, which comprises a treatment for total or partial inactivation of the reactive species present at the surface of the said copolymer, wherein said treatment comprises at least one of:
- (1) one antiradical chemical treatment;
- (2) one electrochemical treatment which makes it possible to modify the degree of oxidation of the said polymer;
- and
- (3) one treatment comprising at least one rinsing operation in the presence of a surfactant.
