✦ Synopsis

The synthesis and solution properties of poly(1,1-diallyl-4-hydropiperazine dichloride) [poly(DAHPD)] ( 3), a dicationic polymer, and poly(1,1-diallylpiperazinium chloride), [poly(DAPC)] ( 4), a bifunctional polymer with trivalent and quaternary nitrogens, and their corresponding copolymers with sulfur dioxide, poly(DAHPD-SO 2 ) (6) and poly(DAPC-SO 2 ) (7), are discussed. Dicationic polymers ( 3) and ( 6) were found to have less pronounced polyelectrolyte effects than their monocationic counterparts ( 4) and ( 7).
