用于烯烃聚合的催化剂组分
Abstract:
一种催化剂组分包括Ti、Mg、Cl和电子给体化合物，该电子给体化合物具有至少0.2cm3/g的孔隙率，且其特征在于，其进一步包括Cu氧化物，前提是当电子给体化合物选自邻苯二甲酸的酯时，孔隙率是至少0.45cm3/g。
Abstract(English):

A catalyst component comprising Ti, Mg, Cl, and an electron donor compound having porosity of at least 0.2 cm3/g and characterized by the fact that it further comprises Cu oxide, with the proviso that when the electron donor compound is selected from esters of phthalic acids, the porosity is of at least 0.45 cm3/g.
