ABSTRACT
Oligomers containing peroxy groups have been synthesized on the basis of epoxides and
organic hydroperoxides. Dependence of reaction rates upon the ratio or starting materials,
nature, quantity, concentration of ammonium salm catalysts, temperature and also nature
of hydroperoxides have been investigated. Ativation energies and effective rate constants of
reactions between hydroperoxides and epoxy resins were calculated. The reaction proceeds by
interfacial catalysis, and therefore with poor yields in solvents which are miscible with
water (acetone and 1.4-dioxane) and with good yields in immiscible solvents (chloroform
and toluene). Structures of the synthesized peroxy oligomers have been confirmed by
IR-spectroscopy.
