Abstract
Several poly(alkoxyphosphazenes) and poly(fluoroalkoxyphosphazenes) were synthesized and allowed to react with various organic nucleophiles. Reactions were carried out at room temperature (25 °C) and at 67 °C in tetrahydrofuran (THF) and were monitored by 31P NMR spectroscopy. The possible use of single-substituent polymers as hydrolytically stable macromolecular intermediates for mixed-substituent polyphosphazene synthesis is discussed, and factors that influence side group replacement in poly(organophosphazenes) are examined. In addition, evidence for a random, irreversible SN2-like mechanism of side group replacement is presented.
