Abstract
La presente invención se refiere a métodos para controlar las propiedades de polímeros en procesos de polimerización que utilizan un catalizador a base de cromo. Una modalidad describe un método para producir una poliolefina que comprende: poner en contacto una mezcla de reacción y un catalizador de óxido de cromo reducido en un reactor de fase gaseosa para producir la poliolefina, en donde la mezcla de reacción comprende un monómero y un comonómero; y cambiar una temperatura de reacción en el reactor de fase gaseosa por aproximadamente 1°C o más por lo cual una relación molar de gas del comonómero a monómero se cambia por aproximadamente 2% o más y un contenido de comonómero de la poliolefina sustancialmente a densidad constante se cambia por aproximadamente 2% o más. También se proporcionan métodos y composiciones adicionales.
