COPOLYMERIZATION STUDY OF 4-VINYLPYRIDINE WITH N-DODECYLACRYLAMIDE

Random copolymers of 4-vinylpyridine and N-dodecylacrylamide were synt hesized by low conversion bulk free radical copolymerization using 2,2 '-azobisisobutyronitrile as initiator. Copolymer compositions were obt ained from NMR spectrometry and elemental analysis. The reactivity rat ios r(VP) and r(C12AM) as determined from the Fineman-Ross, Kelen-Tudo s and Mayo-Lewis methods were found to be 4.13 and 0.27, respectively. The examination of the C-4 resonance peak in C-13 NMR data reveals a triad effect. A good agreement was observed for the experimental triad s fractions determination and their calculation from r(VP) and r(C12). (C) 1997 Elsevier Science Ltd.
