Title (EN) PROCESS FOR PREPARING POLYMERS FROM VINYLAROMATIC COMPOUNDS BY DISPERSION POLYMERIZATION
(FR) PROCEDE DE PREPARATION DE POLYMERISATS A BASE DE COMPOSES VINYLAROMATIQUES PAR POLYMERISATION EN DISPERSION
(DE) VERFAHREN ZUR HERSTELLUNG VON POLYMERISATEN AUS VINYLAROMATISCHEN VERBINDUNGEN DURCH DISPERSIONSPOLYMERISATION
Abstract:
(EN) The invention concerns a process for preparing polymers from vinylaromatic compounds in dispersion, characterized in that polymerization is carried out in the presence of a dispersing aid and a catalyst obtained from: (A) a transition metal complex of the second or eighth subgroup; (B) a cation-forming agent; and (C) optionally an aluminium compound.
(FR) L'invention concerne un procédé de préparation de polymérisats à base de composés vinylaromatiques en dispersion, qui se caractérise en ce que la polymérisation s'effectue en présence d'un auxiliaire de dispersion et d'un catalyseur obtenu à partir A) d'un complexe de métal de transition du deuxième au huitième sous-groupe, B) d'un agent formant des cations et C) éventuellement d'un composé aluminium.
(DE) Die Erfindung betrifft ein Verfahren zur Herstellung von Polymerisaten aus vinylaromatischen Verbindungen in Dispersion, dadurch gekennzeichnet, daß man die Polymerisation in Gegenwart eines Dispergierhilfsmittels und eines Katalysators erhältlich aus (A) einem Übergangsmetallkomplex der II. bis VIII. Nebengruppe, (B) einem Kationen bildenden Agens und (C) gegebenenfalls einer Aluminiumverbindung polymerisiert.
