| titleOfInvention | SOLID CATALYST COMPONENT, PROCEDURE FOR ITS PREPARATION AND USE IN THE POLYMERIZATION OF ETHYLENE AND COPOLYMERIZATION OF ETHYLENE WITH ALPHA-OLEFINS. |
| abstract | A PROCEDURE FOR THE PREPARATION OF A SOLID CATALYST COMPONENT FOR THE POLYMERIZATION OF ETHYLENE AND THE COPOLYMERIZATION OF ETHYLENE WITH ALPHA OLEFINS, COMPOSED OF A PARTICULATE (50-90% BY WEIGHT) SILICY CARRIER AND A CATALYTICALLY ACTIVE PART (50-10 % BY WEIGHT) INCLUDING TITANIUM, MAGNESIUM, CHLORINE AND ALSO ALCOXI GROUPS, PERFORMING THE STAGES: A) A MAGNESIUM CHLORIDE SOLUTION IS PREPARED IN ETHANOL; B) A PARTICULATE ACTIVATED SILICON IS IMPREGNATED USING THE SOLUTION PREPARED UNDER A), SUSPENDING THE SILICONE PARTICLES IN THE SOLUTION; C) A COMPOUND OF HALOGENIC ALCOXIDES AND ALCOXIDES OF TITANIUM AND A SILICON HALIDE IS INCORPORATED INTO SUSPENSION B), WITH AN ATOMIC RELATION BETWEEN MAGNESIUM, IN MAGNESIUM CHLORIDE, AND IT RANGES BETWEEN 12/1 / 2.0 / 1 AND A RELATION BETWEEN THE ATOMES OF SILICE AND ALCOXI GROUPS, IN THE TITANIUM HALOGEN ALCOXIDE OR ALCOXIDE, WHICH RANGES BETWEEN 0.1 / 1 AND 4.0 / 1; D) ETHANOL IS REMOVED FROM THE SUSPENSION OBTAINED IN ENC) BY EVAPORATION; E) THE SOLID OBTAINED IN D) IS REACTIONED WITH AN ALKYL CHLORIDE OF ALUMINUM, WITH AN ATOMIC RELATIONSHIP BETWEEN THE ATOMES OF CHLORINE, IN THE ATHOMIC RELATION BETWEEN THE ATOMES OF CHLORINE, IN THE ALKYL CHLORIDE , AND THE ALCOXI GROUPS, IN THE TITANIUM HALOGEN ALCOXIDE OR ALCOXIDE, WHICH RANGES BETWEEN 0.5 / 1 AND 7.0 / 1; F) THE SOLID COMPONENT OF THE CATALYST IS RECOVERED. |
