Their infrared spectrum changes under UV-irradation and in the heating process have been monitored by ATR-FTIR. Then the aging mechanism has been induced by the infrared spectra before and after aging and their difference spectra. In the condition of UV-irradiation, the polyurethanes degrade to quinoid structures or azo-compounds, which is why polyurethanes' color can easily become yellow.

在紫外线照射下，聚氨酯类有机高分子涂料降解生成偶氮化合物或醌式结构，这也是聚氨酯老化颜色易变黄的原因；丙烯酸类有机高分子涂料降解机理为酯基断裂、形成稳定性较好的内酯，同时伴随侧链断裂的反应。
