摘要：
The invention relates to a method for preparing a particulate carrier for an olefin polymerization procatalyst comprising a transition metal compound reacted for a carrier. In the method a melt Mg Cl2-CH5OH-complex is provided containing in the average 3.3 to 5.5 C2H5OH-molecules as per each MgCl2-molecule, the melt MgCl2-complex is sprayed through a nozzle dispersing it into a chamber, wherein a particulate carrier is formed of it and the ready particulate carrier is removed from the chamber. In the methods known so far difficulties have been encountered in endeavours to produce a carrier having an optimal C2H5OH content. In this invention the problems have been solved by removing by the aid of heat so much C2H5OH from the MgCl2-CH5OH-complex in connection with the spraying that the particulate carrier obtained will continue at the average 2.0 to 3.2 C2H5OH molecules as per each MgCl2 molecule. Such a carrier has a suitable C2H5OH content and a good morphology and spraying it does not raise any difficulties.
摘要（中）：
本发明涉及一种制备用于烯烃聚合主催化剂的颗粒载体的方法，其包括与载体反应的过渡金属化合物。 在该方法中，根据每个MgCl 2分子，提供含有平均3.3至5.5个C 2 H 5 OH分子的熔融MgCl 2 -CH 5 OH络合物，熔融MgCl 2 - 络合物通过将其分散到室中的喷嘴喷雾，其中颗粒载体 由其形成，并且将容器颗粒载体从室中移出。 迄今为止已知的方法已经遇到难以产生具有最佳C2H5OH含量的载体的方法。 在本发明中，通过加热除去MgCl 2 -CH 5 OH络合物中的多少C 2 H 5 OH与喷雾相结合，已经解决了这些问题，所得到的颗粒载体将按每个MgCl 2分子在平均2.0-3.2的C2H5OH分子上继续 。 这种载体具有合适的C2H5OH含量和良好的形态和喷雾性，不会造成任何困难。
