Abstract:
A process for crosslinking a latex (II) prepared from a mixture of:at least one monomer containing ethylenic unsaturation (D), and at least one ethylenically unsaturated monomer containing an epoxide function (E), wherein said latex (II) is reacted with an aqueous dispersion of polymer (I) made by the process of: a) carrying out an emulsion polymerization in water of a mixture of monomers comprising: at least one unsaturated heterocyclic monomer (A) comprising at least one nucleophilic hetero atom, containing at least one exocyclic ethylenic unsaturation, and whose heterocycle comprises an ethylenic unsaturation, and optionally: at least one ethylenically unsaturated monomer (B) containing a (meth)acrylamide, carboxylic acid, carboxylic acid salt, carboxylic ester, organosulphuric acid, organosulphuric acid salt, sulphonic acid, sulphonic acid salt, phosphonic acid, phosphonic acid salt, or vinyl ester function, or an aromatic monomer containing at least one exocyclic ethylenic unsaturation.
