Abstract
Disclosed herein are methods of forming (co)polymers from polymerizable compositions, the methods comprising irradiating the polymerizable compositions with light, wherein the polymerizable compositions comprise a polymerization initiator having an absorption band and exhibiting triplet-triplet annihilation up-conversion and a monomer. Also disclosed herein are methods of additive manufacturing using the methods of forming (co)polymers described herein.
