Abstract
Improvements in the object of the main patent No. 287,177, by "A process for preparing vulcanizable copolymers", especially to prepare linear and unsaturated copolymers of one or more monomers, chosen from ethylene and aliphatic alpha-olefins of the general formula R-CH-CH2, where R is an alkyl group having 1 to 6 carbon atoms, with di- or poly-alkenylcycloalkanes, characterized in that a mixture of said monomers is polymerized in the presence of a catalyst constituted by the product of the reaction between: a) transition metal compounds, and in particular vanadium compounds; b) metal hydrides of groups I, II and III or complex metal hydrides of groups I and III.
