Synthesis of a novel compound based on chitosan and ammonium polyphosphate for flame retardancy applications

In this investigation, a novel compound (NCSAPP) based on chitosan (CS) and ammonium polyphosphate (APP) was synthesized by employing solutions of chitosan and ammonium polyphosphate. The synthesized compound was characterized using FTIR, PXRD, XPS, FESEM, EDX, TGA and a Micro Calorimeter. Finally, NCSAPP was inserted into vinyl ester resin and study the thermal and flammable properties. The FTIR spectrum of NCSAPP suggested the reaction between...
