Abstract

UN COMPONENTE CATALIZADOR SOLIDO PARA LA POLIMERIZACION A PRESION BAJA DE ETILENO Y ALFA-OLEFINAS C3-C6 DENTRO DE POLIOLEFINAS DE PESO MOLECULAR MUY ALTO, ESTA EN LA FORMA DE UN SOLIDO GRANULAR ESFERICO QUE TIENE AREA DE SUPERFICIE DE ENTRE 20 Y 40 M2/G, UN RADIO DE PORO MEDIO DE ENTRE 5000 Y 40000 A Y UNA POROSIDAD DE ENTRE EL 40 Y EL 90 % DE VOLUMEN, Y SIENDO DEFINIBLE POR LA SIGUIENTE FORMULA ( EN PROPORCIONES ATOMICAS ): DONDE X = HF O ZR; ET = GRUPO ETIL; OET = GRUPO ETOXI; Y OR = GRUPO ALCOXI QUE CONTIENE DE 2 A 8 CARBONOS EN LA PARTE ALQUILICA DERIVADA O LINEAL. ASI UN COMPONENTE CATALIZADOR ES OBTENIDO POR PREPARAR UN SOPORTE GRANULAR ESFERICO SOLIDO PARA PULVERIZAR UNA SOLUCION ETANOLICA DE CLORURO DE MAGNESIO, REACCIONANDO DICHO SOPORTE CON UN HAFNIO O ALCOXIDO DE CIRCONIO O HALOGENALCOXIDO, Y FINALMENTE REACCIONAR EL SOPORTE ASI TRATADO CON UN CLORURO DE ALUMINIO ALQUILICO.
