| titleOfInvention | Method for preparing organic disulphides and polysulphides in the presence of polystyrene-divinylbenzene (ps-dvb) resins having guanidine or amidine groups |
| abstract | In a process for the preparation of organic disulphides and polysulphides by reaction of sulphur with a mercaptan or with a polysulphide of lower sulphur order in order to convert it into polysulphide of higher order, or alternatively by reaction of a mercaptan with an organic polysulphide of a high sulphur order in order to convert it into a polysulphide of lower sulphur order, in the presence of a catalyst in the form of a resin with a basic function, the resin is based on a polystyrene-divinyl benzene support functionalized with guanidine or amidine groups, and the reaction is preferably conducted in the presence of methanol. |
