The NMR-MOUSE (R): quality control of elastomers

New applications of the NMR-MOUSE (mobile universal surface explorer) to ci on-destructive quality control of elastomers are reported. One example conc ern the thermal aging of fast clutches which was probed by measurements of H-1 transverse relaxation time. Novel methodological developments show that H-1 double-quantum filtered NMR signals can be generated in the inhomogene ous fields of the NMR-MOUSE for characterization of residual dipolar coupli ngs. This technique was applied to characterize reference natural rubber sa mples with different crosslink density and carbon black and silica fillers. (C) 2001 Elsevier Science Inc. All rights reserved.
