Abstract
Process for obtaining low molecular weight polyolefins especially for the manufacture of low molecular weight polyethylenes produced by the polymerization of olefins, especially ethylene, at pressures of less than 100 atmospheres and at temperatures up to about 100º C with application of such catalysts consisting of in mixtures of metal-organic combinations, especially aluminum alkyl, with metal combinations of the secondary group 4º -6º C. of the periodic system, especially with titanic combinations, characterized in that catalysts of titanic trichloride and dialkyl aluminum monochloride are used which contain on a less titanic trichloride molecule of 0.5 molecule, preferably 0.1-0.3 molecules, of dialkyl aluminum monochloride.
