Disclosed is a method of manufacturing supported metallocene catalyst as in the reaction formula (4) by reacting of metallocene catalyst having an alkoxysilane group with highly reactive siloxane groups on supporting materials, which is produced when the supporting materials are dried at high temperature, not with surface OH groups. By using this method, various side reactions occurred by the reaction of the metallocene compounds with hydroxyl groups could be eliminated.

L'invention concerne un procédé de fabrication d'un catalyseur à métallocène supporté, conformément à la formule de réaction 4. Ledit procédé consiste à faire réagir un catalyseur à métallocène possédant un groupe alcoxysilane avec des groupes siloxanes très réactifs, sur des matériaux de support. Ledit catalyseur est produit lorsque les matériaux de support sont séchés à une température élevée, sans groupes superficiels OH. Ledit procédé permet d'éliminer des réactions secondaires induites par la réaction des composés métallocènes avec les groupes hydroxyles.
