Abstract

The article discusses the results of a study of the effect of the reaction medium composition (distilled water or aqueous solutions of acetonitrile and sodium hypophosphite) on the process of elemental phosphorus polymerization under the influence of accelerated electrons. Carrying out polymerization in an aqueous medium eliminates direct contact with air, which makes the process safer, and adding various chemicals to the solution allows to control the process parameters. It is shown that in an aqueous solution of acetonitrile and sodium hypophosphite, the conversion of phosphorus increases by 7%, and an increase in the polymerization rate is observed compared to using water as a reaction medium at the initial stage. The composition and structure of phosphorus-containing polymers obtained during electron beam polymerization were characterized by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF).
