摘要

PROCEDURE FOR THE OBTAINING OF AN IMPROVED COMPOSITION OF TITANIUM TRICHLORIDE OF STEREO-SPECIFICITY, WHICH HAS APPLICATIONS AS A CATALYST IN THE POLYMERIZATION AND COPOLYMERIZATION OF PROPYLENE. IT CONSISTS OF THE TREATMENT OF A COMPOSITION OF GROSS TITANIUM TRICHLORIDE, OBTAINED BY REDUCTION OF TITANIUM TETRACHLORIDE WITH AN ORGAN-ALUMINUM COMPOUND, WITH A FIRST ELECTRONIC DONOR SELECTED BETWEEN DIALCOHIL-, DIARIL-YETHERY-ALCHER THOSE THAT EACH ALCOHIL GROUP IS C1-10 AND THE ARILS ARE C6-12, AND WITH A SECOND ELECTRONIC DONOR CHOSEN AMONG DIFFERENT ORGANIC COMPOUNDS.
