Abstract
Polymer resins with epoxy groups (PREGs) are synthesized by radical copolymerization of hydrocarbon pyrolysis C9 fraction using 1,2-epoxy-3-tert-butylperoxypropane as the initiator or by copolymerization of the ED-20 epoxy resin modified by tert-butyl hydroperoxide. The effect of the initiator nature and quantity, temperature and reaction time on the yield and characteristic of PREGs are examined. The structure of synthesized products is established by chemical methods and IR spectroscopy. The structurization of ED-22 epoxy resin is studied in the presence of polyethylenamine using 10 and 25 mass% of PREG.
