Abstract
A catalysis system containing an olefin polymerization catalyst having at least one Group 3 to Group 10 transition metal or one of the Lanthanide series of the Periodic Table and an organic support is homogeneous and has particular applicability in the production of polyolefins having narrow molecular weight distribution. The support of the catalysis system is the reaction product of a silicone and a polyamine. The catalysis system has high thermal stability.
