Introduction The presence of certain heterocyclic rings with nitrogen atoms in an organic polymer may significantly improve its thermal stability. For typical polyurethane foams, the upper temperature range of save usage is usually considered to be 90-110°C [1, 2]. This limit can be improved by applying an oligoetherol component containing a thermostable heterocyclic ring with nitrogen atoms, s...
