Transition And Organic Metals Composition Catalysts For Addition Polymerization
(AREA)
Abstract
Process for the manufacture of crystalline copolymers in which two or more vinyl monomers of the type: wherein formula r1 and r2 are the same or different and meaning hydrogen halogen or an alkyl radical in which at least one crystalline isotactic homopolymer whose monomeric units behave as isomorphous units are copolymerized in the presence of a coordination catalyst obtained by contacting a transition metal compound of group ivava or via of the mendeleev periodic system with an organometallic compound of a group iii or iii metal of said system.
