In this paper, the new chelating resin (PSIM) with a polythioether backbone bearing imidazole group is first synthesized by the reaction between polychloromethylthiirane and imidazole.

通过聚环硫氯丙烷与唑进行高分子反应，合成了以聚硫醚为主链、侧链有唑基团螯合树脂（简称PSIM）。

The conversion film is probably constituted of amorphous and pored alloying tannate chelate.

这转化膜很可能是由有一定非晶态合金单宁酸膜层构成.

3, A chelating agent which forms an easily water-soluble metal chelated compound such as nitrilotriacetate (NTA) or ethylene diamine tetraacetate (EDTA) is incorporated in a detergent composition.

在洗衣粉中掺入螯合剂，例如次氮基三乙酸酯（NTA）或者是乙二胺四乙酸酯（EDTA），这些螯合剂易于形成水溶性金属螯合物。
