Title
(EN) SONICATION OF CATALYST IN THE PRODUCTION OF AN UNSATURATED ISOOLEFIN COPOLYMER
(FR) SONICATION D’UN CATALYSEUR DANS LA PRODUCTION D’UN COPOLYMÈRE D’ISO-OLÉFINE INSATURÉE
Abstract
(EN) A process for producing an unsaturated isoolefin copolymer involves: sonicating a solution of an initiator system in an organic solvent, the initiator system comprising a Lewis acid catalyst and a proton source, to produce a sonicated initiator solution, the sonicating performed at an energy input of 100 J/mL or greater, based on volume of the initiator solution; and then, contacting the sonicated initiator solution with a reaction mixture of at least one isoolefin monomer and at least one copolymerizable unsaturated monomer in an organic diluent to produce the unsaturated isoolefin copolymer. Sonication of the initiator solution improves catalyst activity, thereby improving conversion of the monomers during production of the unsaturated isoolefin copolymer.
(FR) Procédé de production d’un copolymère d’iso-oléfine insaturée comprenant : la sonication d’une solution d’un système initiateur dans un solvant organique, le système initiateur comprenant un catalyseur acide de Lewis et une source de protons, afin de produire une solution d’initiateur soniquée, la sonication effectuée à une entrée d’énergie de 100 J/ml ou plus, sur la base du volume de la solution d’initiateur ; et ensuite, la mise en contact de la solution d’initiateur soniquée avec un mélange réactionnel d’au moins un monomère d’iso-oléfine et d’au moins un monomère insaturé copolymérisable dans un diluant organique pour produire le copolymère d’iso-oléfine insaturée. La sonication de la solution d’initiateur améliore l’activité du catalyseur, améliorant ainsi la conversion des monomères durant la production du copolymère d’iso-oléfine insaturée.
