Adsorption interaction of oligomeric sebacic acid peroxide with aerosil surface and its thermolysis in different solvents

Adsorption of oligomeric sebacic acid peroxide on dispersed mineral filler (aerosil) from different solvents was studied. IR spectroscopy was used to study an effect of solvent-peroxide-aerosil adsorption interaction on the p roducts of peroxide thermolysis. Thermodynamic quality of a solvent with re spect to oligoperoxide decreases in benzene > chloroform > dimethylformamid e > dioxane series. Due to competitive adsorption and the change in the con formation of oligomeric molecule, the solvent considerably affects the pero xide decomposition in the presence of aerosil.
