Title (EN) EPOXY COMPOUND CATIONIC POLYMERIZATION INITIATING AGENT AND METHOD
(FR) PROCEDE ET AGENT AMORCEUR DE LA POLYMERISATION CATIONIQUE D'UN COMPOSE EPOXY
Abstract:
(EN) The cationic polymerization of an epoxy compound by opening the cycle thereof is described. The method involves solubilizing a complex consisting of, on the one hand, a boron derivative having the formula B(X)3, wherein X is an anion selected from the group which includes halides and thiocyanates, and on the other, an amine, an ether or an alcohol, in a lactone which is both stable at room temperature, with regard to its homopolymerization, and copolymerizable with the initial expoxy compound.
(FR) L'invention concerne la polymérisation cationique par ouverture de cycle d'un composé époxy. Le procédé consiste à solubiliser un complexe formé, d'une part par un dérivé du bore de formule B(X)3, dans laquelle X est un anion choisi dans le groupe comprenant les halogénures, les thiocyanates, et d'autre part une amine, un éther, ou un alcool, dans une lactone à la fois stable à température ambiante, vis-à-vis de son homopolymérisation et copolymérisable avec le composé de départ époxy.
