Patent

CA 2633427

Complexes of copper and/or zinc with hydrolyzed olefin/maleic anhydride copolymers were solubilized in ammoniacal solution providing preservative solutions that fully penetrate wood. With loss of the ammonia from the wood, the complexes were stably retained in the wood providing a long lasting preservative.

L'invention concerne des complexes de cuivre et/ou de zinc avec des copolymères d'oléfine/anhydride maléique hydrolysés, solubilisés dans une solution ammoniacale pour obtenir des solutions de conservation pénétrant profondément dans le bois. Avec la perte d'ammoniac du bois, les complexes sont retenus de manière stable dans le bois, permettant ainsi d'obtenir un agent de conservation de longue durée.
