Abstract
Although there have been numerous papers concerning the NMR analysis of rubbers, few have specifically considered the use of carbon-13(13C) cross polarization / magic angle spinning (CPMAS) to obtain correlations with physical and mechanical properties. This situation arises, in part, from the fact that rubbery materials, by their very nature, do not lend themselves to efficient cross polarization; high resolution solid state spectra are readily obtainable from simple Bloch decay experiments with minimal broadband proton decouping. However, the CPMAS experiment may be able to shed some light on the nature of the interactions that give rise to significant differences in physical and mechanical properties of rubber blends as a function of composition, degree of degradation, aging, temperature, etc.
