Patent

CA 2623716

The invention relates to compounds embodying amino group-terminal viscosifiers, the resultant products thereof, and the uses thereof. The inventive viscosifiers are provided with formula (I), wherein R1 represents a divalent radical of a carboxyl group-terminal butadiene/acrylonitrile copolymer after removing the terminal carboxyl groups. The disclosed compounds increase the viscosity of the compositions formulated therewith. Compounds containing glycidyl groups are particularly important as resultant products thereof which can be used in thermosetting single-component epoxy resin adhesives.

L'invention concerne des composés promoteurs de résistance terminés par des groupes amino, leurs produits réactionnels et leurs utilisations, ces promoteurs de résistance étant de formule (I), où R1 est un groupe bivalent d'un copolymère de butadiène/acrylonitrile terminé par des groupes carboxyle après élimination des groupes carboxyle terminaux. Les composés de l'invention augmentent la résistance des compositions les contenant. La présente invention porte en particulier sur des composés contenant des groupes glycidyle comme produits réactionnels et pouvant être utilisés dans des adhésifs de résine époxy monocomposants thermodurcissables.
