摘要：
The active carrier particles of even size of the polymerization catalyst are prepared so that a melt of a complex composition is provided having the formula (I): MgCl2 nROH mED, in which ROH depicts an aliphatic alcohol, R is a C1-C6 alkyl, ED depicts an electron donor, n is 1 to 6 and m is 0 to 1; the melt provided is fed to a nozzle (4); the melt is sprayed from the nozzle (4) to the spraying area (5), in which it is divided into fine melt droplets and possibly partly solidifies; the possibly partly solidified melt particles are transferred to a cooled crystallization area (6), where they crystallize to solid carrier particles; and the solid carrier particles are recovered. The melt mentioned is sprayed through a nozzle (4), which is rotated or which has attached to it a member that rotates and throws melt outwards from the rotating center to the spraying area (5).
摘要（中）：
制备具有均匀尺寸的聚合催化剂的活性载体颗粒，使得提供具有式（I）的配合物组合物的熔体：MgCl 2 nROH mED，其中ROH表示脂族醇，R是C1-C6烷基， ED描绘电子给体，n为1至6，m为0至1; 所提供的熔体被供给到喷嘴（4）; 熔体从喷嘴（4）喷射到喷涂区域（5），其中它被分成细熔液滴并且可能部分地固化; 可能部分固化的熔体颗粒被转移到冷却的结晶区域（6），在那里它们结晶成固体载体颗粒; 并回收固体载体颗粒。 所提到的熔体通过喷嘴（4）喷射，喷嘴（4）旋转或附接到其上旋转并从旋转中心向喷出的喷射区域（5）向外熔化的部件。
