Abstract:
1. Nitrile rubber comprising (i) repeating units derived from at least one conjugated diene, at least one α,β-unsaturated nitrile and optionally one or more further copolymerizable monomers, and (ii) one or more structural elements of the general formulae (I), (II), (III), (IV) or (V) in which Z is, a linear or branched, saturated, mono- or polyunsaturated alkyl moiety, a saturated, mono- or polyunsaturated carbocyclyl or heterocyclyl moiety, aryl, heteroaryl, arylalkyl, heteroarylalkyl alkoxy, aryloxy, heteroaryloxy, amino, amido, hydroxyimino, carbamoyl, alkoxycarbonyl, F, Cl, Br, I, hydroxyl, phosphonato, phosphinato, alkylthio, arylthio, sulphanyl, thiocarboxyl, sulphinyl, sulphono, sulphino, sulpheno, sulphonic acids, sulphamoyl, silyl, silyloxy, nitrile, carbonyl, carboxyl, oxycarbonyl, oxysulphonyl, oxo, thioxo, borates, selenates, epoxy, cyanates, thiocyanates, isocyanates, thioisocyanates and isocyanides, R (a), if m≠0, possesses the same definitions as the moiety Z, and M stands for repeating units of one or more mono- or polyunsaturated monomers comprising conjugated or non-conjugated dienes, alkynes and vinyl compounds, or for a structural element which derives polymers comprising polyethers, more particularly polyalkylene glycol ethers and polyalkylene oxides, polysiloxanes, polyols, polycarbonates, polyurethanes, polyisocyanates, polysaccharides, polyesters and polyamides, n and m are alike or different and are each in the range from 0 to 10 000, t is 0 or 1, if n=0, and is 1, if n≠0, and X is C(Z
