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 2
## Abstract Experiments designed to prepare ZieglerβNatta catalysts with controlled particle morphology are reported. Different dealcoholation processes are used on the adduct MgCl~2~βΒ·β__n__EtOH to prepare the catalysts: either thermal treatment or chemical dealcoholation employing different subst
MgC12 as a support for the polymerization catalyst of propylene was prepared by dissolving it in ethanol and by recrystallizing it in n-decane media with vacuum drying. This support was modified by adding ethylbenzoate as an electron-donor, by treating it with triethylaluminium (TEA), and/or by impr
