Abstract:
The present invention relates to a process for producing polyolefin particles from a polyolefin composition, comprising the steps of: a) providing a melted composition of a polyolefin and b) providing particles from the melted composition by: b1) mixing a first flow of a supercritical fluid in the melted composition in a pressure vessel to obtain a solution saturated with the supercritical fluid and b2) passing the solution from the pressure vessel through a throttling device to a spraying tower to expand the solution to obtain the polyolefin particles in the spraying tower, wherein a second flow of a supercritical fluid is injected in the throttling device, wherein the supercritical fluid is a supercritical fluid of a substance selected from the group consisting of CO 2 , NH3, H 2 O, N 2 O, CH 4 , ethane, propane, propylene, n-butane, i-butane, n-pentane, benzene, methanol, ethanol, isopropanol, isobutanol, chlorotrifluoromethane, monofluoromethane, 1,1,1,2-Tetrafluoroethane, toluene, pyridine, cyclohexane, cyclohexanol, o-xylene, dimethyl ether and SF 6  and combinations thereof.

Claim (Index 9):
The process according to  claim 1 , wherein step a) involves polymerization of olefin monomers to obtain the melted composition of the polyolefin and the melted composition is subjected to step b) without solidification before step b).
