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