a Mechanically controlled polymerization under US or ball milling conditions. b The comparison of polymerization kinetics under US and using different piezoelectric materials. c GPC traces for polymerization of DMA under US and using different piezoelectric materials. The measurements were performed using DMF as eluent and PMMA as calibration standard. PNP: piezoelectric nanoparticles. d The comparison of polymerization kinetics under ball milling and using different piezoelectric materials. e Photograph of reaction mixture inside the ball milling jar and temperature changes before and after reaction. f Comparison of polymerization kinetics at different ball milling frequencies.
