ABSTRACT:
Olefins are polymerized in the presence of a homogeneous catalyst represented by the formula LTi(NR.sub.2).sub.3 wherein L is a .sub.II -bonded ligand selected from the group consisting of indenyl, C.sub.1 -C.sub.4 alkyl substituted indenyl, --OSiR.sub.3 substituted indenyl, R is a C.sub.1 -C.sub.4 alkyl group wherein each R attached to the same nitrogen atom is the same, but the R groups attached to different nitrogen atoms can be the same or different from those attached to the other nitrogen atoms.
