摘　　要：DMTDA(3,5-二甲硫基甲苯二胺)是最早用于代替MOCA(3,3'-二氯-4,4'-二氨基二苯甲烷)的液体扩链剂之一,详细介绍了DMTDA的性质、合成、精制及改性工艺。由于DMTDA在室温下为液体,且具有无毒、加工性能好、固化物力学性能优异等优点,因而具有较广阔的应用前景。DMTDA（3,5-dimethylthiotoluenediamine） is one of the earliest liquid chain extenders to replace MOCA.The properties,synthesis,purification and modification of DMTDA are introduced in detail.Because DMTDA is liquid under ambient temperature and possesses the advantages of non-toxicity,better processability,excellent mechanical properties of cured products,and so on,it has wide application prospects.
