本文综述了聚乙烯亚胺的合成、改性反应及其在金属络合过程中的应用研究进展。聚乙烯亚胺是最简单的杂链聚合物之一，它以两种不同的化学结构存在：一种是支化的，是市售的;另一种是线性的，是通过恶唑啉单体的阳离子聚合和随后的聚[（N-酰基亚氨基）乙烯]的水解而合成的。聚（乙烯亚胺）的最显著特征是在聚合物链中同时存在伯，仲和叔氨基，这解释了其基本性质并提供了各种改性反应。本文介绍了支化和线型聚乙烯亚胺的大量合成路线以及类似聚合物的反应。此外，还研究了聚乙烯亚胺及其衍生物与金属离子的络合作用。综述了均相和非均相金属的分离和富集工艺。
This article surveys the research work on the synthesis and modification reactions of poly(ethyleneimine) as well as its applications to metal complexation processes. Poly(ethyleneimine), one of the most simple heterochain polymers exists in the form of two different chemical structures: one of them is branched, which is a commercially available and the other one linear which is synthesized by cationic polymerization of oxazoline monomers and subsequent hydrolysis of poly[(N-acylimino)ethylene]. The most salient feature of poly(ethyleneimine) is the simultaneous presence of primary, secondary, and tertiary amino groups in the polymer chain which explains its basic properties and gives access to various modification reactions. A great number of synthetic routes to branched and linear poly(ethyleneimine)s and polymer-analogous reactions are described. In addition, the complexation of poly(ethyleneimine) and its derivatives with metal ions is investigated. Homogeneous and heterogeneous metal separation and enrichment processes are reviewed.
