WATER-SOLUBLE COPOLYMERS .47. COPOLYMERIZATION OF MALEIC-ANHYDRIDE AND N-VINYLFORMAMIDE
Polymers and High Performance Materials
The free-radical copolymerization of maleic anhydride (MA) and N-vinylformamide (NVF) in homogeneous solution has been studied in the range from 10 to 90 mol % NVF in the feed. The copolymer compositions have been determined from elemental analysis and C-13 NMR. Reactivity ratios were calculated by Fineman-Ross, Kelen-Tudos, and nonlinear least-squares methods and indicate that the monomer pair has a strong tendency to alternate. MA and NVF were found to form a charge-transfer complex in both chloroform and THF. The equilibrium constant and composition of the charge-transfer complex were calculated from the modified Benesi-Hildebrand equation.
