A series of functional polycarbonates, poly((isopropylidene glyceryl glycidyl ether)‐ co ‐(glycidyl methyl ether) carbonate) (P((IGG‐ co ‐GME) C)) random copolymers with different fractions of 1,2‐isopropylidene glyceryl glycidyl ether (IGG) units, is synthesized. After acidic hydrolysis of the acetal protecting groups, a new type of functional polycarbonate prepared directly from CO 2 and glycerol is obtained, namely poly((glyceryl glycerol)‐ co ‐(glycidyl methyl ether) carbonate) (P((GG‐ co ‐GME) C)). All hydroxyl functional samples exhibit monomodal molecular weight distributions with PDIs between 2.5 and 3.3 and M n between 12 000 and 25 000 g mol −1 . Thermal properties reflect the amorphous structure of the polymers. The materials are stable in bulk and solution.
