The thermal decomposition process of simonkolleite, at 500 °C was monitored by EPR and electron microscopy. The experimental data indicate that after an 1 h at 500 °C, three morphologies can be observed from the thermal decomposition of ZHC.

Abstract The kinetics of the reaction of tetramethylthiuram monosulfide (TMTM) differ from that with the disulfide (TMTD). No formation of chemical crosslinks takes place; the sulfur of TMTD adds in correspondence with a curve exhibiting no maximum and the addition differs in the presence and absence of zinc oxide. Simultaneously, the thermal decomposition of TMTM takes place. The electron paramagnetic resonance spectra and the reaction with geraniol show TMTD and TMTM to interact with rubber through a free radical stage.
