USE OF NANOCRYSTALINE CELLULOSE AND POLYMER GRAFTED NANOCRYSTALINE CELLULOSE FOR INCREASING RETENTION IN PAPERMAKING PROCESS

摘要

The present invention provides methods and compositions for improving the properties of a paper substrate. Such a method involves adding an NCC-polymer to a paper substrate. NCC-polymers have unique chemical properties, which improve the wet strength, dry strength and drainage retention properties of the paper substrate.
