Properties of Polyurethane Foams with Oxamide and Borate Groups
The conditions of polyurethane foams preparation with the use of new boroorganic compounds as polyols have been presented. The new polyols have been obtained by two methods: in reactions of N,N’-bis(2-hydroxyethyl)oxamide (BHEOD) and boric acid (BA) with excess of ethylene carbonate (EC) and in reactions of BHEOD esterified with BA with excess of EC. The results of determination of foaming process parameters as well as of investigation of the foams properties have been given.
