Physico-mechanical properties of the products based on filled epoxy-oligomeric mixtures composed of Epidian-5 epoxy resin, oligoesteracrylate TGM-3 and monoperoxide derivative of Epidian-6 epoxy resin (PO) have been investigated. CaCO 3 was used as a filler and polyethylene polyamine was a curing agent. The effect of PO and CaCO 3 on the gel-fraction content and physicomechanical properties was examined. Using a scanning electron microscopy (SEM) the morphology of the samples has been studied.

The mechanism of diepoxide and adipic acid (AA) reaction in the presence of benzyltriethylammonium chloride and 1,4-diazobicyclo[2,2,2] octane has been proposed. The thermal stability of the oligoester obtained via chemical modification of the dioxydiphenylpropane diglycidyl ether with AA and epoxy-oligoesteric mixtures with its participation has been studied. The viscoelastic properties of films based on epoxy-oligoesteric mixtures containing Epidian-5 epoxy resin, TGM-3 oligoesteracrylate, AA modified Epidian-5 and polyethylpolyamine have been determined.

Using light fraction of coal tar (5.75 wt % of coumarone and 44.45 wt % of indene), glycidyl methacrylate and styrene, the coumarone-indene resin with epoxy groups (CIRE) has been synthesized. Monoperoxy derivative of diglycidyl ether Bisphenol A (PO) was used as an initiator. The possible formation of CIRE has been studied on the model systems consisting of PO, glycidyl methacrylate, indene or coumarone, or styrene, or mixture of mentioned compounds. The synthesized product has been investigated as a polymer additive to bitumen-polymer blends (BPB). The effect of CIRE amount, temperature and time on the BPB operational characteristics has been examined. By means of IR-spectroscopy the structures of CIRE, bitumen and BPB were determined.
