Title (EN) METHOD FOR PREPARING POLYTHIOLS
(FR) PROCÉDÉ DE PRÉPARATION DE POLYTHIOLS
Abstract:
(EN) The present invention relates to the method for preparing polythiols comprising the preparation of a sulphydration reaction medium, simultaneously conducting the radical sulphydration reaction of said at least one polyene and the acid catalytic sulphydration reaction of said at least one polyene, and the recovery of a mixture comprising at least two polythiols. The present invention likewise relates to the mixture of polythiols obtained according to said method, as well as to the use of said mixture of polythiols.
(FR) La présente invention concerne le procédé de préparation de polythiols comprenant la préparation d'un milieu réactionnel de sulfhydratation, la conduite simultanée de la réaction de sulfhydratation radicalaire dudit au moins un polyène et de la réaction de sulfhydratation catalytique acide dudit au moins un polyèneet la récupération d'un mélange comprenant au moins deux polythiols. La présente invention concerne également le mélange de polythiols obtenu selon ledit procédé ainsi que l'utilisation dudit mélange de polythiols.
