摘要：
The effect of aromatic ring substitution in the polyester polyol molecule on its physicochemical properties and on the conditions of synthesis, fire resistance and thermal stability of polyurethane foams was investigated. The greater number of terephthalic units in the polyol results in greater viscosity and reactivity during foam formation. The obtained foams were characterized by higher thermal stability (TGA) and fire resistance (oxygen index, single flame test).
