Polyisoolefins are produced using the process according to the invention by polymerising isoolefins, optionally with conjugated or unconjugated dienes and/or cationically polymerisable, mono- or polyunsaturated compounds in solution, in suspension or in the gas phase at temperatures of -100°C to + 200°C and pressures of 0.1 to 100 bar in the presence of an initiator system consisting of aluminium-cyclopentadienyl compounds and boron compounds.
Polyisooléfines produites par polymérisation d'isooléfines, facultativement avec des diènes conjuguées ou non conjuguées et (ou) des composés mono- ou polyinsaturés, polymérisables par voie cationique, en solution, en suspension ou dans la phase gazeuse, à des températures de -100 à +200 °C et à des pressions de 0,1 à 100 bars, en présence d'un système initiateur constitué de composés de type cyclopentadiénylaluminium et de composés du bore.
