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
