Abstract:
The present invention discloses nitrile ligated transition metal-phosphinobenzene-sulfonate complex of formula (I) as catalyst for insertion-copolymerization of mono and bis functionalized vinyl monomers with ethylene or other olefins. In particular, the present invention discloses nitrile ligated metal-phosphinobenzene-sulfonate complex of formula (I) as catalyst for insertion-copolymerization of mono and bis functionalized vinyl monomers with ethylene and or other olefins and to the process for preparation thereof. The invention further discloses a process for the insertion-(co)polymerization of mono and bis functionalized vinyl monomers with olefms catalyzed by the catalyst of formula (I).
