  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...

  We present the synthesis of an oligomer with carboxy and methacrylic groups based on Epidian 6. The effect of the catalyst nature and amount, solvent nature and process temperature on the rate of the reaction between Epidian6 monomethacrylate and adipic acid was examined at 313, 323 and 333 K in the presence of 4-dimethylaminopyridine, 1,4-diazobicyclo[2.2.2]octane, and benzyltriammonium chloride. The synthesized oligomer was characterized...

  Methods of oligomers (polymers) with hydroxy end-groups obtaining are examined. The synthesis of hydroxy-containing oligomers based on epoxy resins is of special attention. The molecules of mentioned oligomers apart from free primary and secondary hydroxy groups contain epoxy, peroxy, carboxy or acrylic groups.
