Process of cross-linking a halogenated polymer by means of a coupling agent based on thiolate

摘要

This invention relates to a process of cross-linking a halogenated polymer be nucleophilic substitution of the halogen atoms by means of a coupling agent constituted by an organo-metallic thiolate, wherein said coupling thiolate is an alkaline or alkaline-earth thiolate not comprising an amine function, of general formula: <IMAGE> in which: Me designates an alkaline or alkaline-earth metal; R1 designates an aliphatic or aromatic radical and; R2 designates a group selected from the group constituted by: <IMAGE> <IMAGE> *R3CCR5 in which R3, R4 and R5 designate an alkyl or aryl group not comprising an amine function.
