Abstract

a presente invenção refere-se à celulose microfibrilada (?cmf?), em particular à celulose microfibrilada que é morfologicamente diferente da cmf convencional conhecida na técnica e/ou que proporcione propriedades de retenção de água melhoradas e/ou propriedades reológicas melhoradas, em particular viscosidade de cisalhamento zero melhorada, 0, (também conhecida como ?viscosidade em descanso?, isto é, a viscosidade na ausência de forças de cisalhamento), em solução, em particular em polietileno glicol (peg) como solvente, vis-à-vis à cmf convencional conforme conhecida na técnica.
