ABSTRACT:
A series of novel amphoteric graft copolymers of xanthomonas hydrophilic colloid and partially N-aminoalkylated acrylamide has been prepared by reacting the corresponding acrylamide copolymer with an alkyl amine and an active aldehyde. The new copolymer is cationized via acidification or quaternization, and is reverted to its anionic form via basification.
