Title: POLYUNSATURATED COMPOUND FOR CURING FLUOROELASTOMER COMPOSITIONS
Abstract:
The invention pertains to a polyunsaturated compound having formula (I) [compound (DAIC-PFPE)]: TA-O-Rf-TA' wherein: - Rf is (per)fluoropolyoxyalkylene chain [chain (Rf)] comprising recurring units having at least one catenary ether bond and at least one fluorocarbon moiety; TA and TA', equal to or different from each other, are selected from the group consisting of: (i) C1-C24 (hydro)(fluoro)carbon groups, possibly comprising one or more than one of H, O, and CI; and (ii) (hydro)(fluoro)carbon group comprising at least one diallylisocyanurate group of formula (A) wherein each of R1, R2, R3, R4, R5, and R6 is, independently, a hydrogen atom or a C1-C3 hydrocarbon group, preferably a hydrogen atom (group TDAIC), with the provisio that at least one of TA and TA' is a group TDAIC, to a process for its manufacture and its use for curing fluoroelastomers, to fluoroelastomer compositions comprising the same, as well as to a process for producing fluororubber mouldings therefrom.
