Dimension of poly(2-methacryloyloxyethyl phosphorylcholine) in aqueous solutions with various ionic strength

The dimension and intermolecular interaction of poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC) in aqueous solutions with various ionic strength was investigated with static and dynamic light scattering. Although PMPC is a polyelectrolyte, its dimension and intermolecular interaction did not change in the aqueous solution of NaCl at 0-0.5 M.
