New organophosphorus polyampholytes containing diaminoalkylphosphinic acid groups

  • Published:
Bulletin of the Academy of Sciences of the USSR, Division of chemical science Aims and scope

Conclusions

  1. 1.

    A new method is proposed for synthesizing polyampholytes, which consists in condensing di- and polyamines with formalin and H3PO2 and which allows the steps of phosphorylation and crosslinking to be combined.

  2. 2.

    Ion exchangers are prepared from polyethylenimines, ethylenediamine, diethylenetriamine, and p-xyly lenediamine.

  3. 3.

    The sorption characteristics of a phosphorylated polyethylenimine with respect to several metal cations have been determined.
