Abstract

UN METODO PARA OBTENER PARTICULAS DE HALURO DE MAGNESIO CRISTALINO, PARA USAR EN LA PREPARACION DE CRISTALES QUE SE USAN EN LA POLIMERIZACION DE (ALFA)-OLEFINAS, PARTICULAS QUE TIENEN LA FORMULA MGNEMXP.YROH, DONDE E ES UN METAL, X ES HALOGENO, ROH ES UN ALCOHOL, N ES NUMERO DE 0,25-6, M ES 0 O 1, P ES UN NUMERO DE 2N A (AM + 2N), DONDE A ES LA VALENCIA DEL METAL E, E Y ES UN NUMERO POSITIVO DE HASTA 6, CONSISTE EN PONER EN CONTACTO UN COMPUESTO DE MAGNESIO DE FORMULA MGNEMXP, DONDE LOS DISTINTOS SIMBOLOS SON COMO SE DEFINIO ANTES, O SU(S) PRECURSOR(ES), CON UN ALCOHOL DE FORMULA ROH PARA FORMAR UNA DISOLUCION, CALENTAR LA DISOLUCION PARA SEPARAR CUALQUIER AGUA PRESENTE, POR AZEOTROPIA, Y PONER EN CONTACTO LA DISOLUCION CALIENTE CON UN HIDROCARBURO INERTE LIQUIDO, PARA PRECIPITAR PARTICULAS CRISTALINAS. LOS PROCATALIZADORES SE FORMAN FUNDIENDO LAS PARTICULAS CRISTALINAS Y AÑADIENDO CANTIDADES ADECUADAS DE UN SOPORTE POROSO A LAS PARTICULAS FUNDIDAS, PARA FORMAR PARTICULAS SOPORTADAS, YHALOGENAR Y TRATAR LAS PARTICULAS SOPORTADAS. CUANDO LOS PROCATALIZADORES SE USAN JUNTO CON UN COCATALIZADOR, TAL COMO UN COMPUESTO ORGANOALUMINICO, SE PUEDEN PRODUCIR POLIMEROS DE MORFOLOGIA MEJORADA.
