AbstractThe preparation of an organophosphorus polyurethane block copolymer of poly‐(ethylene oxide) (PEO) and poly(bis‐p‐carboglycoxyphenyl phenyl phosphine oxide) (PCGPPO) as well as the respective homopolyurethanes is described. The properties of the prepared polymers (melting point, intrinsic viscosity, solubility, and chemical composition) have been determined. Results of thermal and infrared analyses of these polymers are also rep
