  The present invention provides a polyolefin polymer having a bimodal composition with a reduced higher molecular weight component prepared using a self-supported phosphinimine single site catalyst. The catalyst is prepared by precipitating an emulsion of the activated catalyst from a perfluoroalkane continuous phase resulting in spherical catalyst particles having a diameter typically from 5 to 200 μm.

  本发明提供了一种聚烯烃聚合物，该聚合物具有双峰组成，其较高分子量组分的含量降低，使用自支撑膦酰亚胺单位点催化剂制备。该催化剂的制备方法是从全氟烷烃连续相中析出活化催化剂乳液，形成球形催化剂颗粒，其直径通常为 5 至 200 微米。
