  Coumarone-indene resins (CIR) with carboxy groups were synthesized via cooligomerization of unsaturated compounds presented in ligh fraction of coal tar and its fraction boiling out within 423-463 K with the addition of such industrial monomers as styrene, maleic anhydride, glycidyl methacrlate and methacryclic acid. 2,2-azobs 92-methylpropionitrile) in the form of 0,2 M solution in toluene was used as an initiator. The effect...

  The method for obtaining coumarone-indene resins with methacrylic fragments (CIRM) was developed with the addition of methyl ethacrylate, using a light fraction of coal tar and its fraction boiling within 423–463 К. CIRM was obtained via radical cooligomerization using 2,2'-azobis (2-methyl-propionitrile) as the initiator. The effect of the initiator amount, temperature and reaction time on the yield, softening temperature and...

  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...
