Abstract
Procédé perfectionné pour préparer des homopolymères ou copolymères du propylène. On polymérise les monomères dans du propylène liquéfié en présence d'un système catalyseur constitué d'une composition de trichlorure de titane obtenue par réduction du tétrachlorure de titane à l'aide d'un composé d'organoaluminium, suivie d'une activation du produit, d'un compose d'organoaluminium répondant à la formule générale : R2 Alx dans laquelle R représente un groupe alkyle ou aralkyle contenant chacun jusqu'à 18 atomes de carbone et X un atome d'halogène; et d'un ester d'acide carboxylique insaturé, en réglant la production de polymère à au moins 8 kg/g de la composition de trichlorure de titane à des vitesses de polyméLe procédé selon l'invention donne à des vitesses de polymérisation normales des polymères plus stéréo-réguliers.
