Abstract

L'invention concerne des compositions polymériques de matière, ces compositions renfermant des chaînes de polymère d'oléfine dont la masse moléculaire moyenne en nombre (Mn) varie entre 400 et 75.000 environ, et dont le rapport entre les groupes vinyles et le nombre total de groupes oléfines est suivant la formule (1) dans laquelle a = -0,24 et b = 0,8, et dans laquelle le nombre total de groupes vinyles pour 1000 atomes de carbone est supérieur ou égal à 8000 Mn. Cette invention concerne également un procédé de préparation de ces produits polymères, ce procédé consistant à mettre un ou plusieurs comonomères d'oléfine en présence d'un système catalyseur renfermant un composé catalyseur de métal de transition et un alumoxane, dans lequel le rapport entre l'aluminium et le métal de transition est au moins égal à 10:1 et inférieur ou égal à 220:1 (Al:Me). Les conditions opératoires de cette invention permettent d'obtenir les caractéristiques de macromères prévues pour la masse moléculaire comme pour l'insaturation vinylique.
