In the article the results of the modification of stiff polyurethane foam with hydroxyl containing ammonium oligomers have been presented. The influence of duration of synthesis and concentration of N-isobuthyliden-N-2-hydroxylethyl-N-N-2,3-epoxipropyl oligomer (IHEEPAC) on the formation parameters and physical-mechanical properties of stiff polyurethane foams has been shown. As a result of research, it has been determined that ammonium oligomers serve as soft catalyst, coupling agent and fire retardant and simplify the formulation of stiff polyurethane foam.
