摘要:
The invention concerns cellulose microfibrils with modified surface, characterised in that the hydroxyl functions present at the surface of the microfibrils are etherified with at least an organic compound comprising at least a function capable of reacting with said hydroxyl functions, and the degree of surface substitution (DSs) is at least 0.05. The invention also concerns a method for obtaining said microfibrils and their use as agent for modifying viscosity, texture and/or as reinforcing filler.
