Patent

CA 2370350

The invention relates to a polymer which can be obtained in a multi-stage polymerisation process. In a first stage of said process, polymerisation is carried out in the aqueous phase of at least one ethylenically monofunctional compound, optionally with at least one ethylenically difunctional or multifunctional compound in the presence of a polyesterpolyol, polyurethane and/or a polyacrylate. The resulting product is subsequently reacted with a cross-linking agent. The invention also relates to the utilisation of said polymer.

L'invention concerne un polymère que l'on peut obtenir par un procédé de polymérisation à plusieurs étapes, selon lequel: dans une première étape, on réalise une polymérisation en phase aqueuse d'au moins un composé éthyléniquement monofonctionnel, éventuellement avec au moins un composé éthyléniquement bifonctionnel ou multifonctionnel, en présence d'un polyol de polyester, d'un polyuréthanne et/ou d'un polyacrylate; et ensuite on fait réagir le produit obtenu avec un réticulant. L'invention concerne également l'utilisation de ce polymère.
