AbstractCopolymerizations of ethylene with 5-vinyl-2-norbornene or 5-ethylidene-2-norbornene under the action of various titanium complexes bearing bis(beta-enaminoketonato) chelate ligands of the type, [R(1)N=C(R(2))CH=C(R(3))O](2)TiCl(2) (1, R(1)=Ph, R(2)=CF(3), R(3)=Ph; 2, R(1)=C(6)H(4)F-p, R(2)=CF(3), R(3)=Ph; 3, R(1)=Ph, R(2)=CF(3), R(3)=t-Bu; 4, R(1)=C(6)H(4)F-p, R(2)=CF(3), R(3)=t-Bu; 5, R(1)=Ph, R(2)=CH(3), R(3)=CF(3); 6, R(1)=C(6)H(4)F-p, R(2)=CH(3) R(3)=CF(3)), have been shown to occur with the regioselective insertion of the endocyclic double bond of the monomer into the copolymer chain, leaving the exocyclic vinyl double bond as a pendant unsaturation. The ligand modification strongly affects the copolymerization behaviour. High catalytic activities and efficient co-monomer incorporation can be easily obtained by optimizing the catalyst structures and polymerization conditions.
