A process for copolymerizing selectively i) ethylene carbonate with ii) one or more cyclic esters can include contacting the ethylene carbonate with the one or more cyclic esters in the presence of a catalyst. The catalyst can be a Zn-complex with a diaminophenolate ligand (NNO) or a &#x3b2;-diiminate ligand (BDI).

Method of copolymerizing ethylene carbonate with one or more cyclic esters

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. The process may include chemical modification of the hydroxyl chain-end groups into carboxylic groups in the presence of a second catalyst system. The process may include a coupling reaction with at least 2 equivalents of a second cyclic carbonate, enabling coupling with the carboxylic moiety in the presence of a third catalyst system. The process may include polyaddition of a diamine or a polyamine via ring-opening of the second cyclic carbonate, and obtention of poly(carbonate-urethane) or poly(ester-urethane).
