Investigation of synthesis and structural properti̇es of cross-li̇nked polyphosphazene mi̇crospheres deri̇vated from some di̇hydroxy and di̇ami̇ne

In this study, three different cyclomatrix polyphosphazene microspheres were obtained by using precipitation polymerization. method trimer (N3P3Cl6) was reacted with 3-brom-2,5-diaminopyridine 2,6-diaminopyridine and 2,2-dihydroxybiphenyl at the appropriate experimental conditions and those poly(cyclotriphosphazene-co-3-Bromo-2,5-diaminopyridine) (M1), poly(cyclotriphosphazene -co-2,6-diaminopyridine) (M2) and poly(cyclotriphosphazene-co-2,2'-dihydroxybiphenyl) (M3) molecules were synthesized. The analyzes of the microspheres were made by means of SEM-EDX, FT-IR, fluorescence, UV-Vis., XRD, zeta particle size measurement and TGA techniques.
