Title (EN) HIGH-STRENGTH PAPER CONTAINING MODIFIED POLYMER AND PRODUCTION METHOD THEREOF
(FR) PAPIER HAUTE RÉSISTANCE CONTENANT UN POLYMÈRE MODIFIÉ ET SON PROCÉDÉ DE PRODUCTION
Abstract:
(EN) The present invention relates to high-strength paper containing modified polymer characterized in that said paper comprises fibres and modified polymer, of which said modified polymer is modified polymer obtained from a reaction between polymer with active hydroxyl group and cyclic dicarbonyl organic compound. Said polymer with active hydroxyl group can be selected from the group consisting of non-chemically modified synthetic polymer and non-genetically modified natural polymer. Moreover, the present invention relates to method for producing high-strength paper containing said modified polymer.
(FR) La présente invention concerne un papier haute résistance contenant un polymère modifié caractérisé en ce que ledit papier comprend des fibres et un polymère modifié, ledit polymère modifié étant un polymère modifié obtenu à partir d'une réaction entre un polymère à groupe hydroxyle actif et un composé organique de dicarbonyle cyclique. Ledit polymère à groupe hydroxyle actif peut être choisi dans le groupe constitué par un polymère synthétique modifié par un procédé non chimique et un polymère naturel modifié par un procédé non génétique. Un procédé de production du papier haute résistance contenant ledit polymère modifié est en outre décrit.
