SYNTHESIS OF NOVEL OLIGOMERIC PEROXIDES VIA CONDENSATION OF DIHYDROPEROXIDES WITH AROMATIC DIOLS

Novel oligoperoxides (dioxydimethylmethylene-1,4-phenylenedimenthylene ) (EPB) (T-m = 143 degrees C, T-d = 176 degrees C), nedioxydimethylmet hyleneethylenedimethylmethylene) (EPB) (T-m = 100 degrees C, T-d = 175 degrees C) and (dimethylmethyene-2,6-naphthylenedimethylmethylene (NP N) (T-m = 137 degrees C, T-d = 177 degrees C), the products of condens ation of tertiary diols with tertiary dihydroperoxides, were obtained. The structure of the oligoperoxides was confirmed by spectroscopic me thods (IR, NMR). Their thermal properties were studied by differential scanning calorimetry (DSC), and the mechanism of the thermal decompos ition of the oligomeric peroxides was proposed basing on the GC-MS ana lysis of the degradation products.
