Abstract
Procedure for the grading of the molecular weight of olefin polymerizations obtained by the polymerization of olefins, especially ethylene, at pressures of less than about 100 atmospheres and at temperatures up to approximately 100º with the application of such catalysts consisting of mixtures of metal-organic compounds, especially combinations of aluminum alkyl, with metal combinations of the secondary group 4-6 of the periodic system, especially with titanic combinations, for example titanic tetrachloride, the molecular proportion of metal-organic combinations being varied towards the heavy metal combinations for the molecular weight graduation, adding small amounts of oxygen to the polymerization, characterized in that the amount of oxygen that is reacted is increased per kilo of catalyst in order to reduce the molecular weight.
