热失重、红外和气质联用分析表明，MCA／TPU复合阻燃剂对聚甲醛的阻燃作用是由于三聚氰胺氰尿酸盐高温分解并吸热，降低材料燃烧区域的温度；另一方面MCA高温分解生成的三聚氰胺可吸收聚甲醛分解产生的甲醛和甲酸；此外，TPU可提高聚阻燃甲醛的热稳定性，有利于阻燃。

The thermodynamic investigation of adsorptions shows that adsorption of CCTS to Pb~(2+),Cu~(2+),Cd~(2+),Ni~(2+) is spontaneous.Because the values of Gibbs free energy are negative and the calculated entropy values of interactions are positive.However the positive values of the variation in enthalpy show that besides chemisorption, other processes of decalescence, such as physical adsorption and swelling of CCTS were also involved.

CCTS对各重金属离子的吸附热力学分析结果表明：CCTS对各重金属离子吸附熵变△adsS为正值，并且吸附自由能改变量△adsG均为负值，说明CCTS对各重金属离子的吸附是自发进行的，但其吸附焓变△adsH为正值，说明CCTS对重金属离子的吸附不仅仅是化学吸附的过程，还伴随着其他如物理吸附、吸附剂溶胀等吸热过程。
