Oxamide (OD) was hydroxyalkylated with ethylene carbonate (EC). An influence of initial molar ratio of OD:EC, quantity and type of a catalyst as well as temperature on the course of reaction was studied. A structure and composition of products was analyzed by means of IR, 1H NMR, MALDI ToF, GC and GC-MS methods. Participation of by-products was assessed and thermal stability of the reaction products of OD with EC was investigated. Good thermal stability and some other physical properties of the obtained products indicate the possibility of their application in manufacturing of thermostable polyurethane foams.

Key words: oxamide, ethylene carbonate, synthesis of hydroxyethoxy derivatives, structure of products, thermal stability, polyurethane foams
