Supplementation of cellulose nanofibrils with carboxycellulose with low degree of substitution

摘要: The invention concerns compositions containing essentially amorphous cellulose nanofibrils, carboxyl with a degree of substitution not more than o.95 as additive, and optionally at least one co-additive, the content in additive optional co-additive being less 30 wt. % relative to weight nanofibrils co-additive. also method for preparing such compositions, consisting adding substantially nanofibril suspension, co-additive(s), then drying suspension thus additivated. resulting are easily redispersable preserve all their rheological properties.
