摘要
人工合成聚氨酯醇酸，用裂解气相色谱－质谱（ＰＧＣ－ＭＳ）法详细研究其热裂解产物的化学组成，探索其热裂解机理。裂解的主要产物为合成所用的单体甲苯二异氰酸酯（ＴＤＩ）、邻苯二甲酸酐及油脂相应的脂肪酸。
A toluene diisocyanate _ modified alkyd resin was synthesized. The obtained polymer was analyzed by pyrolysis GC _ MS. A mechanism was proposed to explain the pyrolytic procedure. The major pyrolysis products are toluene diisocyanate(TDI), o _ phthalic anhydride, palmitic acid, linolenic acid,linoleic acid, stearic acid.
