| titleOfInvention | Process for the preparation of an unsupported, solid metallocene catalyst system and its use in polymerization of olefins |
| abstract | Process for the preparation of an unsupported, heterogeneous olefin polymerization catalyst system, comprising an organometallic compound of a transition metal of Group 3 to 10 of the Periodic Table (IUPAC 2007) in the form of solid particles comprising the steps of a) preparing a solution (A) comprising ai) an organometallic compound of a transition metal of Group 3 to 10 of the Periodic Table (IUPAC 2007) or of an actinide or lanthanide, a 2 ) a cocatalyst comprising an element of group 13 of the Periodic Table (IUPAC 2007) and a 3 ) a solvent (A-1 ), b) preparing a liquid/liquid emulsion system by dispersing the solution (A) in a solvent (B) essentially immiscible with said solution (A) in the presence of a polystyrene-b-fluoro polystyrene copolymer of the formula (I) in which n is a number from 10 to 100, m is a number from 1 to 40, x is a number from 5 to 16, y is a number from 11 to 33, provided that m, n, x and y are selected in a way that the block copolymer is soluble in the solvent B or the solution A in such an extent that a stable emulsion is formed by adding the block copolymer, b 1 ) the solvent (B) constitutes the continuous phase of the emulsion, b 2 ) the solution (A) constitutes in the form of droplets the dispersed phase and b 3 ) the organometallic compound and the cocatalyst are present in the droplets, c) solidifying said dispersed phase to convert said droplets to solid particles and optionally recovering said particles to obtain said catalyst system; an unsupported, heterogeneous olefin polymerization catalyst, obtainable by the process and the use of the catalyst in olefin polymerization. |
