Title (EN) CATALYTIC SYSTEMS FOR POLYMERISING CYCLIC ESTERS
(FR) Systèmes catalytiques pour la polymérisation d'esters cycliques.
Abstract:
(EN) The invention relates to a catalytic system for polymerising cyclic esters by opening a cycle, including: (i) a metal catalyst of the general formula M(X1 X2 Xm)n, where M is a metal selected from the group including the elements of columns 3-12 of the periodic table as well as Al, Ga, In, Tl, Ge, Sn, Pb, Sb, and Bi, while X1, X2 and Xm are substituents selected from the group including alkyl, aryl, alkoxy, aryloxy, carboxylate or halogen radicals, and m and n are integers between 1 and 6; and (ii) a co-catalyst, characterised in that the co-catalyst is of the aliphatic organosilane type.
(FR) Un système catalytique pour la polymérisation d'esters cycliques par ouverture de cycle comprenant (i) un catalyseur métallique de formule générale M(X1 X2 Xm)n, où M est un métal choisi dans le groupe comprenant les éléments des colonnes 3 à 12 du Tableau Périodique des Eléments ainsi que les éléments Al, Ga, In, Tl, Ge, Sn, Pb, Sb, et Bi, tandis que X1, X2 et Xm sont des substituants choisis dans le groupe comprenant les radicaux alkyles, aryles, alkoxy, aryloxy, carboxylate ou halogène, m et n sont des nombres entiers compris entre 1 et 6 et (ii) un co-catalyseur, caractérisé en ce que le co-catalyseur est du type organosilane aliphatique.
