✦ Synopsis


Surface analytical technique ESCA (electron spectrometer for chemical analysis) has been used for analysis of catalysts used in propylene polymerization. As a result of this analysis it has been shown that productivity of a catalyst can be correlated to Ti/Mg atomic ratio that indicates dispersion of titanium atoms on magnesium support. A quantitative indicator of productivity, i.e. ''titanium index'' has also been evaluated for studied catalysts.

## Abstract The crystal structures of three MgCl~2~**⋅**__n__ EtOH complexes with __n__=1.5, 2.8, and 3.3 have been fully determined. Such complexes are the fundamental precursors for Ziegler–Natta polymerization catalysts used to produce polyolefins on a multimillion‐ton scale worldwide. The ab in

Chlorinated organic polymers were prepared, characterized and used as supports for TiC14. The activity of the new catalysts in the polymerization of ethylene was compared with that observed for TiCl, supported on non-chlorinated polymers. It was found that the new catalysts have initial activities o
