Abstract
The copolymerization of 4-vinylpyridine with acrylamide and N,N-dimeth ylacrylamide by radical initiator varying the feed monomer ratio but k eeping constant the total amount of mole was carried out. The copolyme rization monomer ratios by Fineman-Ross (F-R) and Kelen-Tudos (K-T) me thods were determined. Acrylamide, r(1) = 0.0 (F-R and K-T) and 4-viny lpyridine, r(2) = 1.55 (K-T) and 1.60 (F-R). The thermal stability for the poly(4-vinylpyridine-co-N,N-dimethylacrylamide) was higher than t hat poly(4-vinylpyridine-co-acrylamide).
