Abstract

La présente invention concerne de manière générale la réutilisation, le retraitement ou le recyclage de polymères silicones. Plus précisément, le procédé de la présente invention concerne une méthode de préparation d’organopolysiloxanes OR, par une réaction de dépolymérisation d’au moins un silicone S en présence d’un catalyseur acide et d’au moins un bloqueur de chaîne Bc ayant au moins une fonction siloxane. Ces organopolysiloxanes OR peuvent être utilisés par la suite dans des réactions de polymérisation ou directement dans des formulations diverses.
