Abstract (en)
[origin: WO2016093581A2] Aliphatic polycarbonates are prepared by ring opening polymerization of six-membered cyclic carbonates or various ratio of mixtures of six-membered cyclic carbonates using catalysts. The resulting materials are further polymerized using the extra functional group such as additional 2nd cyclic carbonate, (meth)acrylate and allylate. This process and material(s) obtained provide chlorine (e.g. phosgene and chloroformate)-free and bisphenol-free polycarbonates and their derivatives for environment-friendly applications.
