Abstract
This study describes the radical photopolymerization of acrylate monomers in miniemulsion. Starting from nanosized acrylate droplets (<100 nm) which encapsulate a type I radical photoinitiator (BAPO), UV irradiation led after a few minutes to the formation of polymer nanoparticles of similar size. The present study deals with the kinetics aspects of this reaction and the colloidal properties of the resulting polymer dispersions. Real-time Fourier transform near-infrared spectroscopy in transmission was implemented to follow continuously the fast photopolymerization process. In addition, the spatial resolution of the photoinduced process allowed the online monitoring of the evolution of the miniemulsion size during the UV irradiation through dynamic light scattering.
