    • A method for transitioning from a first to a second catalyst system for the olefin polymerization reaction in one reactor, wherein the first catalyst system is incompatible with the second catalyst system, is described. The method comprises the steps of a) discontinuing a first olefin polymerization reaction performed in the presence of the first catalyst system; and b) performing a second olefin polymerization reaction in the presence of the second catalyst system comprising catalyst components (A) and (B) producing, respectively, a first and a second polyolefin fraction, wherein the M w of the first polyolefin fraction is less than the M w of the second polyolefin fraction and the initial activity of catalyst component (A) exceeds the initial activity of catalyst component (B). Thanks to this method, there is no need to empty the reactor after the first olefin polymerization reaction, and the transitioning time needed to attain the desired quality of the polyolefin obtained in the second olefin polymerization reaction is sufficiently short to permit a quick and reliable change of production.
    • 描述了在一个反应​​器(其中第一催化剂体系与第二催化剂体系不相容的情况下)从用于烯烃聚合反应的第一催化剂体系转化为第二催化剂体系的方法。 该方法包括以下步骤:a)停止在第一催化剂体系存在下进行的第一烯烃聚合反应; 和b)在包含分别产生第一和第二聚烯烃部分的催化剂组分(A)和(B))的第二催化剂体系的存在下进行第二烯烃聚合反应,其中第一聚烯烃部分的Mw小于 第二聚烯烃级分的Mw和催化剂组分(A)的初始活性超过催化剂组分(B)的初始活性。 由于这种方法,在第一烯烃聚合反应之后不需要清空反应器,并且获得在第二烯烃聚合反应中获得的聚烯烃的期望质量所需的转变时间足够短以允许快速可靠的改变 的生产。

    • A method for transitioning from a Ziegler-Natta to a Phillips catalyst system for the olefin polymerization reaction in one reactor, preferably a gas phase reactor, is described. The method comprises the steps of a) discontinuing a first olefin polymerization reaction performed in the presence of the Ziegler-Natta catalyst system; b) performing a second olefin polymerization reaction in the presence of a further catalyst system comprising catalyst components (A) and (B) producing, respectively, a first and a second polyolefin fraction, wherein the M w of the first polyolefin fraction is less than the M w of the second polyolefin fraction and the initial activity of catalyst component (A) exceeds the initial activity of catalyst component (B); and c) performing a third olefin polymerization reaction the presence of the Phillips catalyst system. Thanks to this method, there is no need to empty the reactor after each olefin polymerization reaction, and the transitioning time needed to attain the desired quality of the polyolefin obtained in each olefin polymerization reaction subsequent to the first one is sufficiently short to permit a quick and reliable change of production.
