A study of the effect of polymerization temperature on the microtacticity of poly(propy1ene) prepared using various MgClz-supported catalysts has shown that, in almost all cases, an increase in temperature leads not only to higher proportions of isotactic polymer but also to increased stereoregu1ari
## Abstract This article demonstrates the influence of the molar ratio between diether as internal donor and Magnesium dichloride in processing of the catalyst preparation on the catalytic performance for propylene polymerization with MgCl~2~βsupported ZieglerβNatta catalyst. The effect of electron
The effects of triethers as internal donors on the activity and stereoselectivity of MgCl 2 -supported Ziegler-Natta type catalysts in the propylene polymerization were studied. In particular, we prepared and fully characterized some procatalysts of the type d-MgCl 2 /ID/TiCl 4 , where ID are intern
Propylene polymerization was investigated with the TiC14/MgCI 4 supported catalyst with the stereoregulating donor pair dibutylphtalate (DBPH)/triethoxyphenylsilane (TEPS) in heptane with A1Et 3 as cocatalyst in the presence of hydrogen. It was shown that there is an activation effect by the influen
