Abstract: 
New oligomer with peroxy, primary and secondary hydroxy groups has been synthesized on the basis of peroxy derivative of ED-24 epoxy resin (PO) and PolyTHF-2000 oligoether according to the developed procedure. The effect of the catalysts nature and amount, temperature and process time on the reaction rate has been studied. Benzyltriethylammonium chloride, potassium hydroxide, 1,4-diazobicyclooctane and the mixture composed of benzyltriethylammonium chloride and KOH (molar ratio 1:1) were used as the catalysts. The structure of the synthesized oligomer has been confirmed by the chemical and IR-spectroscopic methods. The synthesized oligomer may be used as an active additive for the production of polymeric films based on ED-20 industrial epoxy resin and TGM-3 oligoesteracrylate.
