Abstract

RESUMEN Un proceso para preparar un componente de catalizador sólido para la producción de polipropileno incluye a) disolver un compuesto de magnesio que contiene haluro en una mezcla; la mezcla incluye un compuesto epoxi, un compuesto de fósforo orgánico y un solvente de hidrocarburos para formar una solución homogénea; b) tratar la solución homogénea con un compuesto de organosilicio durante o después de la etapa de disolución; c) tratar la solución homogénea con un primer compuesto de titanio en presencia de un primer donante de electrones no ftalato y un compuesto de organosilicio para formar un precipitado sólido; y d) tratar el precipitado sólido con un segundo compuesto de titanio en presencia de un segundo donante de electrones no ftalato para formar el componente de catalizador sólido, donde el proceso está libre de ácidos carboxílicos y anhídridos.
