Title (EN) CONTINUOUS TUNING OF Cl:Mg RATIO IN A SOLUTION POLYMERIZATON
(FR) AJUSTEMENT EN CONTINU DE LA PROPORTION CL:MG DANS UNE POLYMÉRISATION EN SOLUTION
Abstract:
(EN) The activity of an in situ prepared Ziegler Natta catalyst in a solution polymerization may be tuned on a continuous basis by monitoring the catalyst activity (conversions) and on a frequent periodic basis incrementally adjusting the alkyl halide in the catalyst to optimize the activity.
(FR) L'activité d'un catalyseur Ziegler-Natta préparé in situ dans une polymérisation en solution peut être ajustée sur une base continue en surveillant l'activité catalytique (conversions) et en ajustant par incréments, sur une base périodique fréquente, l'halogénure d'alkyle dans le catalyseur pour optimiser l'activité.
