Title: Characterization of aged nitrile rubber elastomers by NMR spectroscopy and microimaging

Source: Polymer

Year : 2002

Abstract:

H-1 spin-lattice and spin-spin NMR relaxation times change markedly during the aging of nitrile rubber elastomers. NMR microimaging reveals heterogeneous changes in the aged samples. Aging proceeds mainly via additional chain cross-linking, and scission of the polymer chains does not appear to contribute. T-1 imaging shows that there is no spatial distribution of spin-lattice relaxation times.
