Poly(carbonate-urethane) or poly(ester-urethane) may be characterized in that of carbonate soft segments have molecular weights Mn ranging between 10,000 and 250,000 g/mol. The segments' length may be monitored by the ring-opening polymerization condition. The process of preparing the poly(carbonate-urethane) or poly(ester-urethane) may include immortal ring-opening polymerization of a cyclic carbonate or of a cyclic ester or diester monomers in the presence of a first catalyst system and diols or polyols.
