1 H 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 s

We present a novel NMR approach to the determination of crosslink densities in rubber materials. The method is based on the dipolar correlation effect (DCE) on the stimulated echo examined in a series of rubber samples and linear polyisoprene. The pa

Chain dynamics in a series of natural rubbers with different cross-link densities was studied using the dipolar correlation effect (DCE) on the stimulated echo. In dry samples, amplitudes of the stimulated echo were shown to be affected by attenuatio

Water diffusion into the polymer electrolytes (Pb, Zn)(CF 3 SO 3 ) 2 (PEO) n leads to a dramatic increase of the ionic conductivity. Magnetic resonance imaging, MRI, has been used to study this water diffusion by one-dimensional mapping of properties

A complex aging regime takes place in the course of thermal aging of natural rubber. Depending on the kind and the content of the free crosslinker, the aging temperature, the duration of the aging period and the reactivity of the atmosphere (air or n

Magnetic resonance imaging has been used to follow the time course of lesions induced in the rat brain as an animal model for characterization of the volume of the lesion. The dispersion in spin-spin relaxation has been used to characterize the natur
