Abstract:
A process for the polymerization of olefins, comprising contacting one or more monomers selected from compounds of the formula R.sup.1 CH.dbd.CHR.sup.2 with a catalyst comprising (a) a Ni(II), Pd(II), Co(II), or Fe(II) metal atom, (b) a ligand of the formula I, and optionally (c) a Bronsted or Lewis acid, ##STR26## wherein R.sup.1 and R.sup.2 are each, independently, hydrogen, hydrocarbyl, or fluoroalkyl, and may be linked to form a cyclic olefin;L.sup.1 and L.sup.2 are each, independently, a 5- or 6-membered, monodentate N-donor, heterocyclic ring connected to Q at the position adjacent to the donor nitrogen; andQ is a group of the formula --C(Y)(Z)-- wherein Z is H or a heteroatom connected monoradical and Y is hydrocarbyl or substituted hydrocarbyl.
