Influence of terephthalic and orthophthalic units on the properties of polyols and polyurethane foams

Abstract

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).
