ABSTRACT:
A method for forming supported late transition metal olefin polymerization catalysts is described in which an already formed transition metal complex, usually containing a reactive functional group, is placed on a support containing a complementary reactive functional group. Also described are novel polymerization catalyst components containing late transition metal complexes of neutral tridentate ligands.
