Homogeneous catalysts and olefin polymerization process.

摘要

Olefins are polymerized in the presence of a homogeneous catalyst represented by the formula LTi(NR2)3 wherein L is a pi -bonded ligand selected from the group consisting of indenyl, C1-C4 alkyl substituted indenyl, -OSiR3 substituted indenyl, R is a C1-C4 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.
