Coumarone-indene resins with epoxy groups (CIRE) have been obtained using light fraction of coal tar or fraction with the distillation range of 423–463 K based on it. Styrene and glycidyl methacrylate were used as modifiers. CIRE were synthesized via radical cooligomerization using monoperoxide derivative of dioxyphenylpropane diglycidyl ether (PO) as an initiator. Thermal stability of PO has been studied. The effect of initiator amount, reaction temperature and time on the yield and softening temperature of CIRE has been determined. The structure of the synthesized CIRE was confirmed by IR and 1H NMR spectroscopy.
