Adhesive polymers are formed when polyvalent azides and alkynes are assembled into crosslinked polymer networks by copper-catalyzed 1,3-dipolar cycloaddition. The condensation polymerization is efficiently promoted by Cu ions either leached from the metal surface or added to the monomer mixture, and strong interactions with metal surfaces are provided by the multiple triazole binding elements produced. The adhesive polymers may be formed either as adhesive polymer coatings or as adhesive polymer cement.

La présente invention concerne des polymères adhésifs formés lorsque des azides polyvalents et des alkynes sont assemblés pour former des réseaux polymères réticulés par cyclo-addition de cuivre catalysé 1,3-dipolaire. La polymérisation par condensation est favorisée de manière efficace par des ions Cu soit lixiviés de la surface du métal, soit ajoutés au mélange de monomères; des interactions fortes sont obtenues avec les surfaces métalliques par plusieurs éléments de liaison triazole produits. Les polymères adhésives peuvent être formés soit en tant qu'enrobages polymères adhésifs ou en tant que ciment polymère adhésif.
