Abstract:
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.
