A method for synthesizing cyclic carbonate monomers using carbon dioxide (CO) is provided. The method also includes combining reagents to synthesize the cyclic carbonate monomer, the reagents including a substrate that is a 1,X-diol, where X is between 2 and 5, a base that is a tertiary amine, a promoter that is a multidentate, bis-tertiary amine base where nitrogens are separated by 2 to 4 carbon atoms, a solvent, and CO.

AI assisted cyclic carbonate monomer synthesis

Techniques regarding catalyzing one or more ring-opening polymerizations within one or more flow reactors using one or more organometallic bases are provided. For example, one or more embodiments described herein can comprise a method, which can include forming a polymer, via a ring-opening polymerization within a flow reactor, from a cyclic monomer in the presence of an organometallic base and a primary alcohol initiator.

Polymer technology for use in flow reactors

Techniques regarding the synthesis of cyclic carbonate monomers are provided. For example, one or more embodiments described herein can comprise a method, which can include cyclizing a functionalized diol monomer with N,N'-carbonyldiimidazole, wherein the cyclizing produces a cyclic carbonate monomer and an imidazole carbamate. The method can also include activating the imidazole carbamate with an acid, wherein the activating promotes cyclization of the imidazole carbamate into the cyclic carbonate monomer.
