Samples | M_{n, PAA} | M_{n, PS} | f_{A} | f_{B} |

Sample 1 | 9.6 K | 4.8 K | 0.65* | 0.35^{†} |

Sample 2 | 11.1 K | 5.2 K | 0.75^{‡} | 0.35 |

Sample 3 | 6.8 K | 5.0 K | 0.45^{‡} | 0.35 |

*The volume fraction of PAA block is defined as *M*_{n, PAA}/(*M*_{n, PAA} + *M*_{n, PS}).

†The volume fraction of PS block is defined as *M*_{n, PS}/(*M*_{n, PAA} + *M*_{n, 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 [*M*_{n, PAA}/*M*_{n, PAA (sample1)}] × *f*_{A (sample1)}.
