Abstract
Process for obtaining solid polymers, with a molecular weight greater than 50,000, characterized in that it comprises polymerizing olefins of the formula CH2 = CHR, where R is hydrogen or an alkyl radical with a maximum of 8 carbon atoms, in contact with a prepolymer that it contains from 500 to 10,000 ppm of transition metals belonging to subgroups IVa, Va and VIa of the periodic classification of the elements, the aforementioned prepolymer being obtained previously by polymerization of propylene, if necessary added other olefins of formula CH2 = CHR mentioned above, under a pressure of less than 30 bar, in a dispersing liquid containing a weakly stereospecific catalyst consisting of a compound of one of the transition metals defined above and a cocatalyst consisting of an organic compound of a metal of the groups II and III of the periodic classification of the elements.
