*The volume fraction of PAA block is defined as Mn, PAA/(Mn, PAA + Mn, PS).

†The volume fraction of PS block is defined as Mn, PS/(Mn, PAA + Mn, PS).

‡To consider the length of PAA block in samples 2 and 3, the volume fraction of PAA block in these two samples is calculated to be [Mn, PAA/Mn, PAA (sample1)] × fA (sample1).
