Water-Soluble Copolymers. 67. Polyelectrolytes of N-Vinylformamide with Sodium 3-Acrylamido-3-methylbutanoate, Sodium 2-Acrylamido-2-methylpropanesulfonate, and Sodium Acrylate:  Synthesis and Characterization

Copolymers of N-vinylformamide (NVF) with sodium 3-acrylamido-3-methylbutanoate (NaAMBA), sodium 2-acrylamido-2-methylpropanesulfonate (NaAMPS), and sodium acrylate (NaA) were prepared by free-radical polymerization in aqueous solution using 2,2‘-azobis(N,N‘-dimethyleneisobutyramidine) dihydrochlori...

Zusammenfassung:Copolymers of N-vinylformamide (NVF) with sodium 3-acrylamido-3-methylbutanoate (NaAMBA), sodium 2-acrylamido-2-methylpropanesulfonate (NaAMPS), and sodium acrylate (NaA) were prepared by free-radical polymerization in aqueous solution using 2,2‘-azobis(N,N‘-dimethyleneisobutyramidine) dihydrochloride as the water-soluble azo initiator. Copolymer compositions were determined utilizing 13C NMR by integration of the carbonyl resonances. Reactivity ratios were determined for NVF (M1)/NaAMBA (M2) (the BAVF series) and NVF (M1)/NaAMPS (M2) (the PSVF series). Both series, with r 1 and r 2
