Abstract: Catalysts components for the polymerization of ethylene comprising Ti, Mg, halogen, ORI groups, where RI is a C1-C12 hydrocarbon group optionally containing heteroatoms, having specific relationship among ORI/Ti and Mg/Ti molar ratio and characterized by a specific SS-NMR pattern are particularly useful for preparing narrow MWD crystalline ethylene polymers.
Abstract translation: 用于乙烯聚合的催化剂组分包括Ti，Mg，卤素，ORI基团，其中R1是任选含有杂原子的C1-C12烃基，其具有ORI / Ti与Mg / Ti摩尔比之间的特定关系，并且由特定的SS- NMR图案对制备窄MWD结晶乙烯聚合物特别有用。
