Poly[(ethylene carbonate)‐ co ‐(ethylene oxide)] is synthesized by ROP of 1,3‐dioxolan‐2‐one using 1‐ tert ‐butyl‐4,4,4‐tris(dimethylamino)‐2,2‐bis[tris(dimethylamino)phosphoranylidenamino]‐2Λ5,Λ5‐catenadiphosphazene as the catalyst. NMR spectroscopy shows that the copolymer chain consists of EO‐EC‐EO‐EO sequences. GPC measurements indicate a PDI of 1.43–1.66 and show that the molecular weight increases with monomer conversion. Thermal analysis demonstrates that the copolymer is amorphous with a glass transition temperature of about –42 °C and an onset decomposition temperature of about 200 °C.
