“…The solubilizing power does not seem to be sensitive to the cation, but increases with the radius of the anion. The solution viscosity increases with the concentration of the added salt (37). Near monodisperse zwitterionic polymers have been prepared by the polymerization of sulfobetaine monomers in aqueous media via RAFT (38).…”

“…In the case of free PMAPS, the dependence of R H and intrinsic viscosity of poly(sulfobetaine)s on ionic strength have been well studied by DLS and viscometry measurements; 2,19-23 the unique phase behaviors have been known to depend on salt concentration, 19,23,24 additive salt ion species, 25 temperature, 2 molecular weight and solvent polarity. 20,26 The z-average, mean-square radius of gyration oS 2 4 z and A 2 of PMAPS in an aqueous NaCl solution at 1.0 M and in 2,2,2-trifluoroethanol (TFE) were estimated by Huglin and Radwan, 22,27 who also determined the intrinsic viscosity of PMAPS in a y-solvent.…”

The dimensions and intermolecular interactions of surface-grafted and unbound, free polyampholytes, poly [3-(N-2-methacryloyloxyethyl-N,N-dimethyl) ammonatopropanesulfonate] (PMAPS) and poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC), were estimated in an aqueous NaCl solution over a wide range of salt concentrations (C s ). The free PMAPS and PMPC fractionated by a recycling preparative size-exclusion chromatography system were characterized in aqueous NaCl solutions for C s over a range from 0 to 5.0 M by static light scattering and dynamic light scattering (DLS) measurements. The hydrodynamic radius (R H ) and the concentration coefficient of the diffusion coefficient (k D ) for PMPC were independent of C s , whereas those for PMAPS were strongly dependent on C s . Monodisperse silica nanoparticles immobilized with PMAPS (SiNP-PMAPS) and PMPC (SiNP-PMPC) by surface-initiated atom transfer radical polymerization were characterized in aqueous NaCl solutions for C s over a range from 0 to 5.0 M by DLS and synchrotron radiation small-angle X-ray scattering (SAXS) measurements. The SAXS profiles from SiNP-PMAPS and SiNP-PMPC solutions were well described by the core-shell model, taking into account interacting self-avoiding chains and assuming a Schulz-distributed core with two fitting parameters.
