Aliphatic polycarbonates with Mw greater than 100 000 g mol−1 with satisfactory yield can be synthesized by one-pot melt transesterification of diphenyl carbonate with aliphatic diols at equimolar amounts using Zn(OAc)2 as a catalyst.
A one-pot synthesis was reported to produce hyperstar polymers with high molecular weight, low polydispersity and no detectable star coupling reactions.
