Patent

CA 2429381

Synthetic co-polymers having moieties capable of forming hydrogen bonds, ionic bonds, or covalent bonds with cellulose fibers and paper modifying moieties capable of modifying a paper sheet are disclosed. These synthetic co-polymers are derived from the reaction of an aldehyde functional polymer and an aldehyde reactive paper modifying agent containing a non-hydroxyl aldehyde reactive functional group.

L'invention concerne des copolymères synthétiques à fractions pouvant former des liaisons hydrogène, des liaisons ioniques ou des liaisons covalentes avec des fibres de cellulose, et à fractions de modification du papier pouvant modifier une feuille de papier. Ces copolymères synthétiques sont dérivés de la réaction entre un polymère fonctionnel aldéhyde et un agent de modification du papier réactif aldéhyde contenant un groupe fonctionnel réactif non-hydroxyle aldéhyde.
