Organocatalysis has become a very impressive tool for macromolecular chemistry, as judged by the number of articles published in this field in the last years. A variety of small organic molecules have been used in order to catalyze the polymerization of different monomers. Not only can organocatalysts be employed to promote the ring-opening polymerization of various heterocyclics (e.g. lactones, lactide, cyclic carbonates, epoxides, lactams, cyclocarbosiloxanes), but also to promote the polymerization of vinylic monomers such as (meth)acrylics, or triggering the step-growth polymerization of monomers such as ethylene terephthalate. A key reason for transitioning to organocatalysts is their reduced toxicity in comparison to their metallic counterparts and their ability to be effectively removed from resultant polymers facilitating their recyclability. In that context, polymer scientists and chemical companies have recently dedicated significant efforts into fundamental research on the utilization of organocatalysis into sustainable processes.
