Patent

CA 2756016

The invention relates to a coating material suitable for providing a substrate with an anti-biofouling coating, the coating material comprising a macromolecule comprising: (A) a macromolecular scaffold comprising a reactive group capable of undergoing a Michael type reaction between a Michael type acceptor group and a Michael type donor group, (B) at least one functional moiety attached to the macromolecular scaffold, said at least one functional moiety comprising a hydrophilic moiety, wherein the functional moiety is derivable from a Michael type reaction, involving the reactive group on the macromolecular scaffold and a reactive hydrophilic moiety and (C) at least one moiety capable of crosslinking the coating material.

Cette invention concerne un matériau de revêtement permettant de doter un substrat d'un revêtement antifouling biologique, ledit matériau de revêtement comprenant une macromolécule comprenant: (A) une structure macromoléculaire comprenant un groupe réactif capable de subir une réaction du type Michael entre un groupe accepteur du type Michael et un groupe donneur du type Michael, (B) au moins un fragment fonctionnel attaché à la structure macromoléculaire, au moins ledit fragment fonctionnel comprenant un fragment hydrophile, et pouvant être dérivé d'une réaction du type Michael, impliquant le groupe réactif sur la structure macromoléculaire et un fragment hydrophile réactif et (C) au moins un fragment capable de réticuler le matériau de revêtement.
