SOLID-STATE C-13 NMR-STUDIES OF VULCANIZED ELASTOMERS .9. TMTD-VULCANIZED CIS-1,4-POLYBUTADIENE AT 75.5 MHZ

Solid state NMR studies have previously been performed to characterize the network composition of variously vulcanized natural rubber, polybutadiene rubber, and butyl rubber samples. Preliminary evaluation of two-dimensional NMR imaging techniques to investigate the spatial distribution of network structures in these systems have also been made previously. This paper expands on the information base and summarizes the results of NMR analysis of samples cured with the organic sulfur-donor agent tetramethyl thiuram disulfide.
