Potentiometric titration curves of AEMA and DMAEMA monomers and homopolymers. The solutions were acidified to pH 1 with 1 M HCl and titrated with 0.20 mol L–1 NaOH. The pKa of the AEMA and DMAEMA were 9.32 and 8.62, respectively, while the pKa of the primary and tertiary amine homopolymers were 8.46 and 7.84, respectively.
