Abstract
Procedimiento perfeccionado para polimerizar alfa-olefinas a baja presiónen presencia de un catalizador estereoespecífico para obtener polimerizados que tienen un alto contenido en polímero isotácticocaracterizado porque la polimerización es efectuada en ausencia de disolventes y a una temperatura de 20 a 90º Csiendo el monómero mantenido en la fase líquida.
