Abstract
Cellulose microfibril reinforced polyers, corresponding latices, powders, films and rods, and uses thereof. Polymer/cellulose composites are prepared using individualized cellulose microfibrils with a high form factor, e.g., tunicin microfibrils, as the reinforcement. For this purpose, reinforced latices consisting of a polymer latex and a stable aqueous suspension of said microfibrils are used. Said polymers have a wide variety of uses, particularly in paints and nanocomposites.
