Abstract

940,137. Polymerizing alpha-olefins. MONTECATINI SOC. GENERALE PER L'lNDUSTRIA MINERARIA E CHIMICA. May 24, 1962 [May 29, 1961], No. 19986/62. Addition to 891,646. Heading C3P. Polymers of alpha-olefins are made by polymerizing the monomeric olefin in the presence of a catalyst system comprising activated TiCl 3 , an aluminium dialkyl monohalide, and a complex obtained from a zinc dihalide e.g. ZnCl 2 , and a nitrogen-containing organic base in amount such that the molar ratio of the zinc compound to the TiCl 3 is at least 0À05. The preferred olefin is propylene. The polymerization is generally effected in a hydrocarbon diluent. The nitrogencontaining organic base may be pyridine, quinoline, or isoquinoline. The polymer is recovered by conventional techniques, and it may be separated into fractions by solvent extraction methods. Activated TiCl 3 is described by Natta, G., in J. Polymer Sci., 1961, 51, 399-410.
