Fig. 4 Diagram of states for solution of block copolymers with pH-sensitive PE blocks. Coor-
dinates are ( a ) polymer concentration C and salt concentration ion (at constant buffer pH); ( b )

polymer concentration C and pH (at constant salt concentration). Dashed lines in ( b ) indicate shift
of the boundaries of different regimes upon increasing hydrophobicity of the blocks B
