Preparation of a solid catalyst system

摘要

Process for the preparation of a solid catalyst system comprising the steps of
€¢ generating an emulsion by dispersing a liquid clathrate in a solution wherein
(i) the solution constitutes the continuous phase of the emulsion and
(ii) the liquid clathrate constitutes in form of droplets the dispersed phase of the emulsion,
€¢ solidifying said dispersed phase to convert said droplets to solid particles and
€¢ optionally recovering said particles to obtain said catalyst system,
wherein
€¢ the liquid clathrate comprises a lattice being the reaction product of aluminoxane, an organometallic compound of a transition metal of Group 3 to 10 of the Periodic Table (IUPAC 2007) or of an actinide or lanthanide, and a further compound being effective to form with the aluminoxane and the organometallic compound the lattice, and a guest being an hydrocarbon compound, and
€¢ the solution comprises a silicon fluid and a hydrocarbon solvent.
