Title (EN) SILICONE-POLYETHER COPOLYMER COMPOSITION, METHOD OF PREPARING SAME, AND SEALANT
(FR) COMPOSITION DE COPOLYMÈRE SILICONE-POLYÉTHER, SON PROCÉDÉ DE PRÉPARATION ET PRODUIT DE SCELLEMENT
Abstract:
(EN) A silicone-polyether copolymer has the formula (X-D2)g-Y, where each X is an independently selected silicone moiety having a particular structure, D2 is a divalent hydrocarbon group, subscript g is greater than 1, and Y is a linear or branched polyether moiety. A method of preparing the silicone-polyether copolymer comprising reacting a polyether compound and an organosilicon compound in the presence of a hydrosilylation-reaction catalyst. A sealant is also disclosed, the sealant comprising the silicone-polyether copolymer and a condensation-reaction catalyst.
(FR) L’invention concerne un copolymère silicone-polyéther qui a pour formule (X-D2)g-Y, dans laquelle chaque X représente une fraction silicone sélectionnée de manière indépendante, présentant une structure particulière, D2 représente un groupe hydrocarboné divalent, l'indice g est supérieur à 1, et Y représente une fraction polyéther linéaire ou ramifiée. L'invention concerne également un procédé de préparation du copolymère silicone-polyéther consistant à faire réagir un composé polyéther et un composé organosilicium en présence d'un catalyseur de réaction d'hydrosilylation. L'invention concerne également un produit de scellement, le matériau de scellement comprenant le copolymère silicone-polyéther et un catalyseur de réaction de condensation.
