| titleOfInvention | SOLID CATALYTIC COMPONENT FOR POLYMERIZATION AND COPOLYMERIZATION OF ETHYLENE, AND PROCEDURE FOR OBTAINING IT. |
| abstract | Process for obtaining a solid catalytic component for the polymerization and copolymerization of ethylene, in which a particulate silica support (65 to 85% by weight) is impregnated with a catalytically active portion (15 to 35% by weight) that includes titanium , magnesium, chlorine, alkoxy groups, and at least one organometallic compound of Group 13 of the Periodic Table, the process comprising the following steps: (a) impregnating a particulate activated silica using a solution of an organometallic compound of the Group 13 of the Periodic Table in an amount comprised between 0.1 and 1 mmol of the organometallic solution per mmol of OH on the silica surface, in an inert organic solvent; (b) remove the supernatant liquid from step (a); (c) preparing a solution obtained by reacting at least one magnesium compound, selected from magnesium halides and magnesium alkoxides, in an amount between 0.0024 and 0.24 g of magnesium per g of silica, and therefore less a titanium compound, selected from titanium alkoxides and titanium halogenoalkoxides, in an amount comprised between 0.01 and 1 g of titanium per g of silica; (d) impregnate the silica obtained in (b) using the solution prepared in (c); (e) optionally reacting the solid obtained in (d) with a reducing agent selected from the group consisting of Na alkyls, Li alkyls, Zn alkyls, Mg alkyls, and the corresponding aryl derivatives, compounds of Grignard of the type RMgX and polyhydrosiloxanes, in which R represents a linear or branched alkyl group, containing from 1 to 10 carbons, or aryl derivatives, and X represents a halogen atom, and alkylaluminum or silicon halide compounds; (f) reacting the solid obtained in (d) or (e) with a halogenating agent selected from the group consisting of methylaluminum dichloride, methylaluminum sesquichloride, isobutylaluminum dichloride, isobutylaluminum sesquichloride, ethylaluminum dichloride (EADC) , diethyl aluminum chloride (DEAC), ethyl aluminum sesquichloride (EASC), SiCl4, SnCl4, HCl, Cl2, HSiCl3, aluminum chloride, ethylboro dichloride, boron chloride, diethylboro chloride, HCCl3, PCl3, POCl3, acetyl chlorides , thionyl chloride, sulfur chloride, methyltrichlorosilane, dimethyldichlorosilane, TiCl4, VCl4, CCl4, t-butyl chloride, n-butyl chloride, chloroform, 1,1,1-trichloroethane, 1,1,2-trichloroethane, 1 , 2-dichloroethane and dichloromethane; (g) maintaining the solid obtained in (f) at a temperature of 60 ° C to 120 ° C from 0.5 hours to 5 hours; (h) wash the solid obtained in (g) with an inert organic solvent; (i) optionally washing the solid obtained in (h) with a solution of one or more organometallic compounds of Group 13 of the Periodic Table in an amount between 0 and 3 g of the organometallic compound per g of the dry catalyst component obtained. |
