Abstract
Process for the preparation of linear and high molecular weight polymers, of regular structure, of at least one styrene substituted in the core with one or more lower alkyl groups or one or more halogen atoms, and/or at least one vinyl naphthalene or vinyl tetrahydronaphthalene, characterized in that it comprises polymerizing the monomer or monomers in the presence of a catalyst obtained by contacting a compound of a metal of group iva, va or via of the periodic table according to mendeleeff with an organometallic compound of an element of group ii or iii of said table.
