Abstract
Process for the manufacture of solid polymers, with an average molecular weight of more than 50,000, from olefins of the formula CH2 = CHR, where R is a hydrogen atom or an alkyl radical with a maximum of 8 carbon atoms, characterized in that it consists of Olefins polymerize in the absence of a liquid dispersant of a different nature from that of the olefins to be polymerized and in contact with a prepolymer containing 500 to 10,000 ppm of transition metals belonging to the Ivb, Vb and VIb subgroups of the periodic classification of the elements, obtaining said prepolymer by polymerization of an olefin in a dispersing liquid containing a catalytic system consisting of at least one compound of a transition metal as defined above and at least one organic compound of a metal of groups II and III of the periodic classification of the elements, and the prepolymer thus obtained is then separated gone from the dispersant liquid, and then it is subjected to an extraction operation by means of an anhydrous solvent.
