The urethane elastomers based on 4,4′‐diphenylmethane diisocyanate (MDI), oligo (ethylene adipate) (OEA) with different chain extenders, and dibromohexane or ammonium salt were synthesized. Their mechanical and thermal properties were studied by stress‐strain analysis, thermomechanical methods, and differential thermal analysis. It was demonstrated that the incorporation of ionic groups in the structure of urethane elastomers due to the reaction of dibromohexane with a tertiary amine or urea NH group improves their tensile strength and thermal resistance.
