  The present invention describes a process for preparation of catalyst component comprising contacting magnesium based precursor along with an internal donor based on phenylene dioates with an acyl halides in a solvent to obtain a solid precatalyst component; and contacting the solid precatalyst component with transition metal compound to obtain the catalyst component. The present invention also relates to a process for preparation of a catalyst system from said catalyst component and preparation of a polyolefins having free flowing characteristics with bulk densities (BD) of at least about 0.3 g/cc from the catalyst system.

  本发明描述了一种制备催化剂组分的方法，包括将基于镁的前体物与基于苯二酸酯的内部供体接触，并在溶剂中与酰卤反应，以获得固体前催化剂组分；并将固体前催化剂组分与过渡金属化合物接触，以获得催化剂组分。本发明还涉及从该催化剂组分制备催化剂体系的方法，以及使用该催化剂体系制备具有自由流动特性且体积密度（BD）至少约为0.3 g/cc的聚烯烃的方法。
