摘要：
Process for supportation of a catalyst system comprising at least two different active catalyst components on a support wherein in an earlier supportation step a first active catalyst component is applied to the support at a first predetermined temperature and in a later supportation step a second active catalyst component is applied to the support at a temperature which is at least 20° C. lower than the first predetermined temperature.
