Синтез полиэдральных олигосилсесквиоксанов, содержащих изоцианатные группы в органическом обрамлении силсесквиоксанового ядра

Abstract

A mixture of polyhedral oligosilsesquioxanes containing isocyanate groups in the organic shell of a silsesquioxane core (РOSS-NCO) is synthesized by the reaction of a mixture of polyhedral oli-gosilsesquioxanes with tertiary amine, primary and secondary hydroxylic groups in the organic part of the molecule (РOSS-M) with excess of tolulene diisocyanate. Its derivative is obtained by the reaction of РOSS-NCO with N,N-dimethylaminoethanol. The structure of the synthesized compounds is characterized by GPC, ¹H NMR, and IR spectroscopy.
