Abstract: A catalyst composition for the polymerization of propylene is provided. The catalyst composition includes one or more Ziegler-Natta procatalyst compositions having one or more transition metal compounds and one or more esters of aromatic dicarboxylic acid internal electron donors, one or more aluminum containing cocatalysts and a selectivity control agent (SCA). The SCA is a mixture of an activity limiting agent and a silane composition. The catalyst composition has a molar ratio of aluminum to total SCA from 0.5:1 to 4:1. This aluminum/SCA ratio improves polymerization productivity and the polymer production rate. The catalyst composition is self-extinguishing.

Abstract: The present invention relates to &agr;-olefin/vinyl aromatic monomer interpolymers with characteristic signals in their carbon 13 NMR spectra. In particular, ethylene/styrene copolymers of the present invention have peaks in the carbon 13 NMR spectra which appear in the chemical shift range 43.70-44.25 ppm, preferably from 43.75-44.25 ppm and 38.0-38.5 ppm, said peaks being at least three times the peak to peak noise. The interpolymers are prepared by polymerizing the appropriate mixture of monomers in the presence of a catalyst such as racemic-(dimethylsilanediyl(2-methyl-4-phenylindenyl)) zirconium dichloride. The polymers of the present invention posses increased modulus as determined from both tensile stress/strain and dynamic mechanical data at comparable vinyl aromatic monomer levels.
