CH3CH2ONa-initiated condensation copolymerization of DEC (diethyl carbonate) and flexible aliphatic diol for semi-crystalline high-molecular-weight poly(alkylene carbonate)

Based on CH3CH2ONa-catalyzed two-step-transesterification reaction from DEC and α,ω-alkanediol (BD, PD or HD), semi-crystalline poly(alkylene carbonate)s with Mn up to 104 g/mol are obtained, respectively.72
