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.Cellulose microfibrils I comprising ether groups that replace hydroxyl groups on the surface, their preparation process and their use, wherein said hydroxyl groups are substituted by ether groups with a degree of surface substitution (DSs) by less equal to about 0.05 and because said ether groups are essentially located on the surface of said microfibrils. Such microfibrils are used as reinforcement of composite materials and as a paint texture agent.
