Urethane Formation Reaction in Oligodienes Obtained in Solutions of Alcohols under the Action of Hydrogen Peroxide

摘要

The kinetics of the urethane formation reaction between hydroxyl-containing oligodienes HTPB obtained by the action of hydrogen peroxide in alcohol solutions, and phenyl isocyanate has been studied. The kinetic features of this reaction consisting of non-monotonic change in the conversion of hydroxyl groups and a stepwise character of the reaction in the coordinates of the second-order equation were presented and discussed. These features were explained by the course of the reaction in the associates of polar hydroxyl groups in the non-polar oligodiene matrix.
