A study has been made on Ziegler Natta polymerization, under various conditions, using styrene and 2-vinylpyridine as monomers, A1EI~-VCI~ as catalyst system and the heterocyclic bases, pyridine, z-and 7-picolines as co-catalyst. The influence of the temperature and times for formation of the active

✦ Synopsis
A~traet--Polymerizations of styrene and 2-vinylpyridine were undertaken with AIEh-VCI 4 as homogeneous catalyst, under several sets of conditions. Conversion was related to the formation time of the catalytic species. Relative crystallinity and average molecular weight for the polymers obtained at 25", 50 °, and 90 ° are given. Influences of donor ligands such as pyridine and 2-and 4-methylpyridine on the polymerizations have been considered.
