USE OF NANOCRYSTALINE CELLULOSE AND POLYMER GRAFTED NANOCRYSTALINE CELLULOSE FOR INCREASING RETENTION, WET STRENGTH, AND DRY STRENGTH IN PAPERMAKING PROCESS

摘要

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