Photoiniferter polymerization

WebIn here, we describe the visible light induced polymerization of several methacrylates via trithiocarbonate photoiniferter polymerization. In all cases, the method affords polymers with comparatively narrow molecular weight distribution ( Đ = 1.20–1.30) even for moderate molar mass values above 10 kg mol −1 , whereby full monomer ...
