Abstract

Microfibrillas de celulosa I que comprenden unos grupos éteres que sustituyen en superficie a unos grupos hidróxilos, su procedimiento de preparación y su utilización, en las que dichos grupos hidróxilos están sustituidos por unos grupos éteres con un grado de sustitución de superficie (DSs) por lo menos igual a aproximadamente 0,05 y porque dichos grupos éteres están localizados esencialmente en la superficie de dichas microfibrillas. Dichas microfibrillas se utilizan como refuerzo de materiales compuestos y como agente de textura de pinturas.
