- Preparation and characterization of bis‐phosphonated polycarbohydrates Kamila Sadowska Marta Prześniak‐Welenc Marcin Łapiński Biopolymers AbstractA 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. 10.1002/bip.23607 http://onlinelibrary.wiley.com/termsAndConditions#vor
