Anionic and cationic polymers are prepared by vinyl polymerizing a 2-alkenyloxazoline or 2-alkenyloxazine and reacting the resulting polymer which contains pendant oxazoline or oxazine moieties with a monobasic salt of sulfurous acid or a tertiary amine salt. Optionally, the 2-alkenyloxazoline or 2-

Anionic and cationic polymers are prepared by vinyl polymerizing a 2-alkenyloxazoline or 2-alkenyloxazine and reacting the resulting polymer which contains pendant oxazoline or oxazine moieties with a monobasic salt of sulfurous acid or a tertiary amine salt. Optionally, the 2-alkenyloxazoline or 2-alkenyloxazine can be polymerized with another ethylenically unsaturated monomer and/or a small amount of polyvinyl crosslinking monomer; and the resulting polymer is reacted with the desired salt to yield an anionic or cationic polymer.
