Architecture of Star-block Copolymers Consisting of Triblock Arms via a N,N-diethyldi-thiocarbamate-mediated Living Radical Photo-polymerization and Application for Nanocomposites by Using as Fillers

1 Results Highly branched poly(methyl methacrylate) (PMMA) stars were prepared by one-pot approach based on N,N-diethyldithiocarbamate-(DC) mediated living radical photo-polymerization.Soluble alternating hyperbranched microgel formation was initiated fast with preferential consumption of inimer 4-vinylbenzyl N,N-diethyldithiocarbamate (VBDC) and 4,4′-bismaleimidediphenylmethane (BMIM) in the presence of an excess of methyl methacrylate (MMA),PMMA arms could then grow from DC groups of microgel as macro...
