Abstract

Mejora en el método para la polimerización catalítica de etileno solamente o la copolimerización de etileno con alfa-olefinas que contienen de 3 a 6 átomos de carbono, caracterizada porque la polimerización se lleva a cabo en presencia de un catalizador constituido por un cromato de sililo con la fórmula: **(Fórmula)** en la cual cada R es un radical hidrocarbilo que contiene de 1 a aproximadamente 14 átomos de carbono, depositado sobre un soporte de sílice de elevada área superficial, conteniendo dicho soporte, tratado por calor previamente a una temperatura de 500-100ºC, aluminio y titanio.
