Abstract

On produit un copolymère de propylène à blocs en réalisant une étape de polymérisation antérieure continue de propylène seul ou de propylène et d'une faible quantité d'éthylène et on réalise une étape de polymérisation postérieure (copolymérisation discontinue) d'éthylène et de propylène. On règle la quantité d'agent d'amélioration d'activité pour la copolymérisation discontinue et/ou la durée de polymérisation de cette copolymérisation en fonction de la quantité de suspension transferée du réservoir de polymérisation continue au réservoir de copolymérisation discontinue .
