    • A method for making polymerization catalysts is disclosed which comprises contacting a soluble complex prepared from the combination of a metal dihalide and a transition metal compound with a particulate material comprising zirconium phosphate and then reacting the resulting mixture with an organoaluminum halide to produce a catalyst precursor. The catalyst precursor is then contacted with a halogen containing compound selected from halides of Groups IVA and VA to produce the catalyst. Novel catalysts prepared in accordance with the invention method, novel polymerization processes therewith and novel polymers having relatively high melt flow rates while retaining good mechanical strength are also disclosed.
    • 公开了一种制备聚合催化剂的方法,其包括将由二卤化金属和过渡金属化合物的组合制备的可溶性络合物与包含磷酸锆的颗粒材料接触,然后使所得混合物与有机铝卤化物反应以产生催化剂前体。 然后将催化剂前体与选自IVA和VA族的卤化物的含卤素化合物接触以产生催化剂。 还公开了根据本发明方法制备的新型催化剂,其新颖的聚合方法和具有较高熔体流动速率同时保持良好机械强度的新型聚合物。
