DETERMINATION OF THE SEQUENCE DISTRIBUTION AND IONIZATION CONSTANT OF POLY(ACRYLIC ACID-CO-VINYLAMINE) BY C-13 NMR.

Academic Article

Abstract

  • Three copolymers of poly(acrylic acid-co-vinylamine) containing amino groups were synthesized from poly(acrylic acid) by means of the Schmidt reaction. These copolymers were analyzed by C-13 NMR and the results compared with the previously analyzed homopolymers. The various comonomer sequence distributions were identified by means of peak areas. It was determined that the reactivity was not significantly influenced by the triad tacticity of the parent poly(acrylic acid), the final copolymer is characterized by an essentially alternating sequence, and there is extensive lactam formation between neighboring carboxyl and amino groups.
