摘要

研究了聚酯多元醇分子中芳香环取代对其理化性质、合成条件、阻燃性和热稳定性的影响。多元醇中对苯二甲酸单位的数量越多，泡沫形成时粘度越大，反应性越强。所得泡沫具有较高的热稳定性(TGA)和耐火性(氧指数、单火焰测试)。

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

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).
