Initially, research into NCA’s was impeded by a myriad of issues, including a lack of technology needed to characterize compounds.[1][12] As time went on, NCA’s were mostly used as monomers in polymerization techniques beginning around the 1950’s.[3] These methods were inefficient however due to multiple side reactions that would lead to early termination or undesired products.[3][12][8] Due to the poor dispersity of these products, focus turned to tuning the NCA polymerization process.
