✦ Synopsis

Polymerizations of 4-vinylquinoline and 4-vinylpyridine were carried out with the A1Et3-VC13 catalyst system at various temperatures. The influence of the molar ratio of the catalyst system on conversion, for both monomers, was analysed. The influences of the formation time of catalytic species, polymerization time, temperature and the molar ratio of pyridine as donor ligand have been examined under various experimental conditions. Interpretation of results was made on the basis of trigonal active centres and steric hindrance for both monomers.
