Popis: | Random copolymers of 4-vinylpyridine and N -dodecylacrylamide were synthesized by low conversion bulk free radical copolymerization using 2,2′-azobisisobutyronitrile as initiator. Copolymer compositions were obtained from NMR spectrometry and elemental analysis. The reactivity ratios r VP and r C 12 AM as determined from the Fineman-Ross, Kelen-Tudos and Mayo-Lewis methods were found to be 4.13 and 0.27, respectively. The examination of the C-4 resonance peak in 13 C NMR data reveals a triad effect. A good agreement was observed for the experimental triads fractions determination and their calculation from r VP and r C12 . © 1997 Elsevier Science Ltd |
