Transition And Organic Metals Composition Catalysts For Addition Polymerization
(AREA)
Abstract
A process for preparing vulcanizable, amorphous, high molecular weight and essentially linear copolymers of dialkenyl or polyalkenyl-cycloalkanes with one or more monomers selected from the group consisting of ethylene and the aliphatic alpha-olefins of the general formula R-CH = CH2 , wherein R is a herelic group with 1 to 6 carbon atoms, characterized in that the monomer mixture is polymerized in the presence of a catalyst constituted by the product of the reaction between; a) transition metal compounds of groups IV and V b) Metallo-organic compounds of metals of groups I, II and III or of complex metallo-organic compounds of metals of groups I and III.
