Abstract

An olefine polymerization catalyst is prepared by contacting an organo-metallic compound of a Group I, II or III metal (Mendeleef Table) with a compound (other than an oxide) of at least two metals, on at least two compounds each of a different metal, the metals being selected from Group IV(a), V(a), VI(a), VII(a) or VIII, having a maximum electron removal work below 5eV (Lange), and removal potentials below 8V for the first electron and 18V for the second electron. The metals thus defined are Ti, Zn, V, Fe, Co, Cr and Mn. Specified combinations are aluminium triethyl and various pairs of chlorides or oxychlorides of the Group IV(a) to VIII metals. Olefines specified are ethylene, propylene, butene, styrene, butadiene and isoprene. The polymers obtained are predominantly isotactic. In examples, polymerization is effected in bulk, in benzene or in n-heptane under an inert atmosphere. Specifications 810,023, 828,791 and 849,100 are referred to. Reference has been directed by the Comptroller to Specifications 778,639, 799,850 and 824,418.
