✦ 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.
