Abstract
The effect of aromatic ring substitution in the polyester polyol molecule on its physicochemicalproperties and on the conditions of synthesis, fire resistance and thermal stability of polyurethanefoams was investigated. The greater number of terephthalic units in the polyol results in greater viscosityand reactivity during foam formation. The obtained foams were characterized by higher thermalstability (TGA) and fire resistance (oxygen index, single flame test).
期刊介绍：
