    Randomly branched (arborescent) poly(sodium 2-acrylamido-2-methyl-N-propanesulfonates) (NaPAMPS) were synthesized via self-condensing vinyl polymerization using activators generated by electron transfer atom transfer radical polymerization (AGET ATRP). The controlled self-condensing AGET ATRP of NaAMPS was realized in the presence of 2-(2-bromopropionyloxy)ethyl acrylate (BPEA) as a branching monomer (inimer) in water/pyridine mixed solvents. The content of BPEA in the reaction feed was varied. The definite evidence of highly branched structure of NaPAMPS was provided by the dependence of radius of gyration R-g on weight-average molecular weight M-w and by small-angle X-ray scattering (SAXS) analysis. Molecular parameters conformation and dynamics of the branched NaPAMPS in dilute salt-free solutions and in the presence of a salt were elucidated by static and dynamic light scattering and SAXS.
