Influence of Media on Processes of Radiation-Induced Polymerization of White Phosphorus

Abstract

Radiation-induced polymerization of elemental phosphorus in the presence of ionic liquids(IL) was investigated. Composition, structure, and properties of the products-phosphorus-containing polymers (PCPs)-were examined by the methods of physicochemical analysis. It was found that the structure of ionic liquid and its concentration in the media has a significant influence on the polymerization rate. Some kinetic properties of the radiation-induced polymerization process of the elemental phosphorus in the presence of ionic liquids in the mixed solvent “dimethylsulfate (DMSO)/benzene” were determined (reaction rate, effective rate constant, reaction orders).

Keywords:
