摘要:
Disclosed is a method of preparation of spherical support for olefin polymerization catalyst, wherein the support is produced by continuously introducing a mixture of metal magnesium and alcohol into a reactor containing a mixture comprising halogen compound and alcohol and optionally dialkoxymagnesium, and then the magnesium is reacted with the alcohol in the presence of the mixture comprising halogen compound and alcohol and optionally dialkoxy-magnesium. By the method, it is possible to control the reaction rate appropriately and to improve particle shape and particle size distribution of the resulted dialkoxymagnesium support.
