(84) 1-1 © N (54) Title: CATALYST SYSTEM FOR THE PRODUCTION OF POLYOLEFINS AND METHOD OF MAKING AND USING © SAME kr) I I - (57) : Catalyst systems for polymerization of mixtures comprising an olefm include a selectivity control agent comprising 0 ---- at least one silicon-containing compound containing at least one Cl-C10 alkoxy group bonded to a silicon atom and an amount of GC one or more agent compounds. The agent compound comprises C2-C13 mono- or polycarboxylic esters of aliphatic C2-C7 carboxylic 1-1 © acids and inertly substituted derivatives thereof. One or more polymerization catalysts may also be present. A polymerization process f'1 includes contacting an olefm or a mixture of the olefm and one or more copolymerizable comonomers under polymerization conditions C with the catalyst composition.
