Abstract:
The present invention is directed to an amphoteric polymer, a method for preparing an amphoteric polymer, use of the amphoteric polymer for emulsifying an alkenyl succinic anhydride. The present invention also provides an alkenyl succinic anhydride emulsion prepared using the amphoteric polymer, and a method for sizing paper using an alkenyl succinic anhydride emulsion prepared using the amphoteric polymer. The amphoteric polymer of the present invention is obtained by copolymerization of cationic monomers, non-ionic monomers, and anionic monomers.
