Preparation and characterization of bis‐phosphonated polycarbohydrates

Abstract

A simple, cost-effective, one-pot method was proposed to introduce bis-phosphonic groups onto alginic acid and carboxymethyl cellulose (CMC). New derivatives were characterized by means of nuclear magnetic resonance, X-ray photoelectron, and attenuated total reflectance Fourier transform infrared spectroscopy. These analyses confirmed the successful transformation of carboxylic groups present in alginic acid and CMC into bis-phosphonic groups. Additionally, thermogravimetric analysis coupled with differential scanning calorimetry was employed to investigate the thermal properties of the bis-phosphonic derivatives of alginate and CMC. The results clearly demonstrate the char-forming ability of both studied bis-phosphonated polycarbohydrates, suggesting their potential as intumescent materials.
