The synthetic progress of polysuccinimide using maleic acid as original material was studied by two steps of aminization and polymerization. Changes of reactant and product composition in aminization reaction step was studied by using bromine value analysis method. It was found that amine salt and amide were main products in this step.

对以马来酐为原料合成聚琥珀酰亚胺的两个反应过程进行了研究，通过溴价测定法研究了胺化反应阶段反应物及产物各组分的变化情况，确定胺化反应阶段的产物组分主要是胺盐和酰胺。

Sodium 2-Acrylarnido-Acetate has been synthesized through the reaction of Aminoacetic acid with acryloyl chlorine, then Copolymer of sodium 2-acrylamido-acetate and dimethyl diallyl ammonium chloride with acrylamide had been prepared by free radical polymerization using (NH4)2S2O8 and NaHSO3 as the free radical initiator in water solution.

本论文首先以氨基乙酸和丙烯酰氯为原料制备丙烯酰胺基乙酸钠单体，然后以丙烯院胺丙烯酰胺基乙酸钠和二甲基二烯丙基氯化铵为单体，(NH4)2S2O8和NaHSO3为自由基引发剂，采用水溶液聚合法合成丙烯酰胺／丙烯既胺基乙酸钠／二甲基二烯丙基氯化铵共聚物。

For example edible is amylaceous (general composition is straight catenary) degree of polymerization is 200, 980 or the limits of opposite element quality is 32000, 160000, at this moment the color that iodine and amylaceous bag close matter is blue, this is the iodine that we often say encounters starch to change blue.

例如食用淀粉的聚合度是200—980或相对分子质量的范围是32000—160000，这时碘和淀粉包合物的颜色是蓝色，这就是我们常说的碘遇淀粉变蓝色。

Iodine encounters boiling amylaceous solution not colour developing, be in with starch at this moment the color that degree of polymerization and iodic bag close matter is concerned.

碘碰到沸腾的淀粉溶液不显色，和淀粉在这时的聚合度和碘包合物的颜色有关。

Starch has gelatinization effect in hot water, elevatory and amylaceous grain is easier when temperature burst, the degree of polymerization that brings about starch is reduced, the opposite element quantity of amylaceous grain is reduced, as the change of amylaceous grain, the package that iodine and starch fashion adds up to content color to also can produce a series of change.

淀粉在热水中具有糊化功能，温度时升高淀粉颗粒更轻易破裂，导致淀粉的聚合度降低，淀粉颗粒的相对分子量减小，随着淀粉颗粒的变化，碘和淀粉形成的包合物颜色也会发生一系列变化。
