丙烯腈-丁二烯-苯乙烯

The writer chose the hollowness fiber filter module of the two kinds of material: Polypropylene Cyanotype and Polymer SipHon to preceded the research.

试验研究选择了聚砜和聚丙烯腈两种不同材质的中空纤维膜组件进行了研究。

The fabrication of fibers was attempted. The copolymers, the copolymers containing MOCT and the copolymer films containing MOCT were characterized by using Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy, Differential Scanning Calorimetry, Thermogravimetric Analyzer and X-ray Diffraction etc. The conclusions were summarized as following,1. The AN/MMA copolymers were testified that copolymerization of most AN and MMA occurred and the ratio of AN and MMA in copolymer was less than the ratio of monomers. With the increase of the contents of MMA, the viscosity of copolymer solution, molecular weight and decomposition temperature of copolymers increase.

通过傅立叶变换红外光谱、扫描电子显微镜、差示扫描量热分析、热重分析、X-射线衍射分析等测试方法对得到的AN／MMA共聚物、含有正十八烷微胶囊的共聚物以及共聚物膜等进行了测试和分析，得到如下的研究结论： 1、丙烯腈—甲基丙烯酸甲酯之间发生了聚合反应，共聚物的组成比略小于投料比；共聚物的粘度和分子量随着第二单体MMA加入量的增加有增大的趋势；第二单体加入量的增大使得共聚物的分解温度升高，通过热重分析证实当AN／MMA摩尔比为85／15时，共聚物的耐热稳定性较高。

The removal rate of AN was more than 98%and the concentration in effluent reached to less than 5 mg/L.

丙烯腈的去除率在98%以上，出水浓度低于5 mg/L，达到了排放控制的要求。

At present, the output of hydrocyanic acid produced as a by-product in production of acylonitrile is reached 100000t/a, a suggestion is offered on producing iminodiacetic acid by direct synthesis based on hydrocyanic acid for those enterprises having advantage in hydrocyanic acid resource.

On the basis of this observation, we studied the hydrolysis of PAN in alkaline solution.

在此基础上，论文研究了聚丙烯腈膜在碱溶液中的水解反应，通过控制水解反应的温度和时间制备了一系列具有不同水解度的PAN超滤膜。

The effects of reaction time, hydroxylamine hydrochloride concentration and reaction temperature on the reaction were investigated.

通过研究聚丙烯腈纤维与盐酸羟胺的反应制备偕胺肟基螯合纤维，考察了反应时间、盐酸羟胺浓度、反应温度对反应的影响规律。

A new inequilateral organic polyamine, 2-aminoethyl-bi(3-aminopropyl)amine, was synthesized by the additional and hydrogenation reaction of aminoacetonitrile with acrylonitrile.

利用氨基乙腈及丙烯腈的亲核加成、氢化反应合成了一种新的不等臂有机多胺化合物2-氨基乙基-二（3-氨基丙基）胺。

Provides BS, ISO and the AATCC propylene nitrite separtor inserter.
