摘要：

The results of esterification of N, N'-bis(2-hydroxypropyl) oxamide (BHPOD) with the use of boric acid (BA) have been described. Subsequently hydroxypropyl derivatives of oxamide (OD) modified with boron as products of the reaction of BHPOD esterified boric acid with an excess of propylene carbonate (PC) have been obtained. Foamed polyurethane materials received with the use of these derivatives as polyol components and diisocyanate 4,4'-diphenylmethane exhibited higher thermal stability and compressive strength compared to the foams obtained with hydroxypropyl derivatives of OD which do not contain boron.
