Facile preparation of long-chain aliphatic polycarbonates containing block copolycarbonates via one-pot sequential organic catalyzed polymerization of macrocyclic carbonates and trimethylene carbonates

Abstract

A universal and effective approach was reported to synthesize block copolycarbonates containing long-chain aliphatic polycarbonates and PTMC segments using the ROP differences between macrocyclic and small cyclic carbonates with TBD as catalyst.
