Synthesis of Selenium-containing Polymers

Abstract

Polymers containing selenide pendents have been synthesized by the reactions of organic selenium compounds, such as selenols, diselenides (in the presence of reductant), and selenide Grignard's reagent, with three kinds of chlorine-containing polymers. As selenols are easily oxidized by a trace amount of oxygen in a solution, experimental procedure was rather difficult. Despite the reaction with Grignard's reagent appears to be most reasonable, economical and convenient, an appreciable side reaction occurs and the selenium content of the polymer becomes low. The selenide polymer, with higher degrees of substitution and conversion, was obtained by the reaction of diselenide with polymers in the presence of reductant. A,
