ABSTRACT:
Process for the modification, e.g. cross-linking, of polymers containing C.dbd.C or C.tbd.C unsaturation by reacting them with nitrile sulphides or precursors therefor. A preferred system entails mixing the polymer with a 5-R-substituted-1,3,4-oxathiazol-2-one and heating the mixture to a temperature at which the nitrile sulphide is generated.
