RESINS OF AMPHOTERIC ALDEHYDIC POLYMERS AND USE OF SUCH RESINS AS RESINS WITH TEMPORARY STRENGTH IN WET STATE AND STRENGTH IN DRY STATE FOR PAPER

摘要

This invention relates to resins useful for imparting dry-strength and temporary wet-strength to paper, the process of incorporating these resins into paper and the paper produced containing the resins. The resin comprises an amphoteric polymer produced through polymerization of an anionic monomer, a monomer containing aldehyde functionality and a cationic monomer.
