Activity ratio of acrylonitrile-ammonium itaconic acid copolymerization system and the changes of AIA content in two methods of comnonomer adding were studied in this paper.

研究了丙烯腈－衣康酸铵共聚体系的竞聚率和不同加料方式下聚丙烯腈树脂中衣康酸铵含量的变化规律。

In this work, properties of acrylonitrile-co-ammonium of itaconic acid system was studied in detail in order to accumulate foundation for high performance carbon fibers.

本文将衣康酸铵作为第二单体，系统研究了丙烯腈-衣康酸铵二元体系作为炭纤维前驱体的特点，以期为开发适用于高性能炭纤维的二元PAN原丝奠定必要的基础。

By using cadmium acetate as catalyst, polyitaconic anhydride was prepared through ring opening polymerization of itaconic anhydride.

以衣康酸为原料合成了衣康酸酐，并在乙酸镉的催化作用下通过开环聚合得到了聚衣康酸酐。

In this study, an index evaluation system of itaconic acid was established according to the current situation of IA and the correlative laws in China. For the first time, a complete research on the IA production from this point of view was carried out, finding out the problems in the process of IA production, and then the project was advanced. All the research were begun with the data from laboratory and escalated to the industry scale. During the past three years, some of the work were applied successfully to industry.

根据现有衣康酸生产的现状和我国清洁生产相关的法律法规，建立了衣康酸清洁生产的指标评价体系，并以此为依据对现有衣康酸生产的工艺首次从清洁生产的角度进行了系统的研究，找出现有工艺中存在的问题，分析问题产生的原因，并提出衣康酸清洁生产工艺改进的方案，本研究沿着先从实验室研究规模入手得到相关的基础数据，再以此为依据逐步扩大实验规模直至在大规模生产中取得应用，通过三年的研究与实践，其中的多项研究成果已经在生产中得到应用，并取得了良好的效果。

We can get chitin and protein from the mycelium using the waste alkali and waste hydrochloric acid, so as to enhance its comprehensive benefits.7 The project of the comprehensive treatment of the mother liquorFor the reason of recrystallization, a large amount of mother liquor were produced with the production of IA, except for IA, it also contain residua sugar, mineral and colloid, which could prevent the recovery of IA crystal.

利用回收的树脂再生酸、碱从菌丝体中分离出甲壳素和菌体蛋白，提高的菌体的综合效益。7、衣康酸提取母液的综合治理方案由于衣康酸的提取采用的是重结晶法，因此，生产过程中会产生大量的母液，母液中除了含有衣康酸外，还含有残糖、无机离子及少量小分子胶质物质等，这些成分的浓度相对较高，抑制了母液中衣康酸的结晶和提取，导致这部分母液只能排放，不仅使衣康酸的提取率降低，也加重了污水处理的负荷。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
