Title (EN) OPEN CHAIN MODIFIED CELLULOSIC PULPS AND METHODS OF MAKING AND USING THE SAME
(FR) PÂTES CELLULOSIQUES MODIFIÉES À CHAÎNE OUVERTE ET LEURS PROCÉDÉS DE FABRICATION ET D'UTILISATION
Abstract:
(EN) The present disclosure generally relates to open chain modified cellulosic pulps and methods for making and using the same. More specifically, the open chain modified cellulosic pulps described herein may be made by oxidation of a cellulosic pulp, followed by reduction of the oxidized groups, resulting in a modified pulp having an improved open chain configuration that may be more efficiently converted into cellulosic derivative products. This disclosure further relates to improved cellulosic derivative products made therefrom, for example, cellulose esters, cellulose ethers, and regenerated cellulose products.
(FR) La présente invention concerne généralement des pâtes cellulosiques modifiées à chaîne ouverte et leurs procédés de fabrication et d'utilisation. Plus spécifiquement, les pâtes cellulosiques modifiées à chaîne ouverte de la présente invention peuvent être produites par oxydation d'une pâte cellulosique, puis par réduction des groupes oxydés, donnant une pâte modifiée présentant une meilleure configuration de chaîne ouverte qui peut être plus efficacement convertie en produits dérivés cellulosiques. L'invention concerne également des produits dérivés cellulosiques fabriqués à partir desdites pâtes, par exemple, des esters de cellulose, des éthers de cellulose, et produits de cellulose régénérée.
