    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 CO2, NH3, H2O, N2O, CH4, 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 SF6 and combinations thereof.

    Abstract: The present invention relates to a process for recycling polyolefin, comprising the steps of: 1) feeding a solid post-consumer polyolefin composition comprising polyolefin and contaminants and a flow of an extraction fluid to an extractor having a pressure of 100-1000 bar and a temperature of 20-80° C. to obtain a solid extracted composition, 2) melting the solid extracted composition to obtain a melted composition, 3) providing particles from the melted composition by: 3a) mixing a flow of a supercritical fluid in the melted composition in a pressure vessel to obtain a solution saturated with the supercritical fluid and 3b) passing the solution from the pressure vessel through a throttling device to a spraying tower to expand the solution to obtain polyolefin particles in the spraying tower.

    Abstract: The present invention relates to an ethylene copolymer comprising: (iv) ≥78.0 and ≤99.9 mol % of recurring units derived from ethylene; (v) ≥0.10 and ≤20.0 mol % of a recurring units derived from a comonomer A according to formula (I) wherein R1 is a moiety comprising 1-30 carbon atoms; R2 is selected from —H or —CH3; R3 is selected from —O—, —(CO)—(NH)— or —(CO)—O—; n=0 or 1; and m≥1 and ≤10; and (vi) ≥0.01 and ≤2.00 mol % of a recurring units derived from a comonomer B according to formula (II) wherein R1 is a moiety comprising 1-30 carbon atoms; each R2 may individually be selected from —H or —CH3; each of R3 is individually selected from —O—, —(CO)—(NH)— or —(CO)—O—; n=0 or 1; p=0 or 1; and m≥1 and ≤10; the mol % of each of (i), (ii) and (iii) being related to the sum of the mol % of (i), (ii) and (iii), the sum of the mol % of (i), (ii) and (iii) adding up to 100 mol %. Such ethylene copolymers have a reduced peak melting temperature and reduced enthalpy of fusion, indicating that these ethylene copolymers have a reduced degree of crystallinity and improved clarity and contact angle, combined with a desired melt mass-flow rate.
