Since the acceptance of the macromolecular theory, the effects of external force on polymers have been actively studied. Initially, mechanical force and flow fields applied to polymers were recognized as the main causes of the degradation and decomposition of polymers. In recent years, the relationship between polymers and external forces has been reevaluated as a source for functionalization of polymers. Recently, we have found that photopolymerization with scanning light irradiation, termed “SWaP”, induces molecular diffusion and a molecular flow field, resulting in the alignment of the anisotropic molecules. In this study, we report the highly efficient polymerization behavior under the flow field induced by SWaP and the applicability to the reversible addition-fragmentation chain transfer polymerization, one of the precision radical polymerization techniques.
