peroxide oligomers

The thermal decomposition of pendant peroxy groups in a cooligomer of maleic anhydride with 5-(tert-butylperoxy)-5-methylhex-1-en-3-yne as well as in its amino derivatives immobilized on different silica surfaces, has been investigated using a complex thermo-gravimetric analysis. Two types of silica: fumed (aerosil) and precipitated (white carbon black) ones have been surface modified by this cooligomer via diverse techniques. It has been established that in all the cases the cooligomer decomposition on the silica surface complies with the first-order kinetics.
