The kinetics of propylene polymerization using a prepolymerized high-active T i c & catalyst with an EtzAICl cocatalyst are investigated. The effect of various parameters such as Al/ T i ratio, pressure, temperature, hydrogen, and polymerization time on the rate of polymerization and yield are exami

## Abstract **Summary:** Self‐supported and MgCl~2~‐supported Ziegler‐Natta catalysts, produced by two catalyst synthesis methods are compared. Borealis Polymers OY (Finland), who supplied the catalysts, developed the catalyst synthesis methods. The first method (Method One) is based on an emulsion
Grignard reagent PhMgCl was added during the preparation of the catalyst system MgCl 2 /di-n-butyl phthalate (DNBP)/TiCl 4 {AlEt 3 /diphenyl dimethoxyl silane (DPDMS) to improve its performance. It was found that PhMgCl could enhance both the activity of the catalyst and the isotacticity of the prod
