摘要：

The thermal behaviour of samples of maleic anhydride oligomer (MAO), fulvic acid (FA) and humic acid (HA) of well-known origins has been studied. FA crystallizes very easily: m.p. = 441 K, melting DELTA-H = 230.5 J g-1. The thermogravimetric analysis revealed similar behaviour for FA and MAO, which decompose with comparable rates. In contrast, the decomposition of HA proceeds more slowly and with formation of a 10-20% residue.
