介绍了衣康酸的制备工艺。其主要可通过微生物发酵法、柠檬酸合成法和顺酐合成法制得。衣康酸分子中含有2个羧基和1个碳碳双键，可通过与其他单体共聚合制备新型高分子材料。如将衣康酸与丙烯腈共聚可制备改性聚丙烯腈原丝；将衣康酸与二元醇缩聚可制备新型聚酯材料；将衣康酸、丙二醇和癸二酸缩聚可制备具有形状记忆功能的新型生物基聚胺材料等等。另外，利用衣康酸多官能团特点，还可以对部分高分子材料灵活改性。如衣康酸接枝聚烯烃和尼龙改善材料的相容性；衣康酸改性丁苯胶乳可大大提高其机械稳定性、抗冻性等性能。由于石化资源的不可再生性，伴随着衣康酸的产能增加，成本降低，利用衣康酸单体合成的新型高分子材料具有广阔的应用前景。

The paper gave a brief introduction to the preparation of itaconic acid. It could be produced by microorganism fermentation method, critic acid synthesis method and maleic anhydride synthesis method. Itaconic acid contains two carboxyl groups and double bonds, which can be used for synthesizing polymers and copolymers with other monomers. For example, itaconic acid could be copolymeized with acrylonitrile to prepare caron fiber and copolymerized with dihydric alcohol to prepare polyester. Many polymer materials can also be modified by itconic acid. Polyolefin and nylon materials could be grafted by itaconic acid to improve the compatibility, and styrenebutadiene latex could be modified by itaconic acid to improve its performance greatly. Due to the nonrenewablity of fossil energy, as the capacity of itconic acid increasing, the biobased material like itaconic acid has a bright future.
