| PS-b-P4VP(59)a | 18,500 | 40,500 | 59,000 | 1.10 | 563 | ≈0.33 |
| PS-b-P4VP(75)a | 24,000 | 51,000 | 75,000 | 1.10 | 716 | ≈0.33 |
| PS-b-P4VP(120)a | 38,000 | 82,000 | 120,000 | 1.28 | 1145 | ≈0.33 |
| PS | 51,000 | - | - | 1.05 | 490 | - |
| P4VP | - | 48,000 | - | 1.07 | 457 | - |
a The numbers in parentheses denote the total Mn of BCPs; b φ are the volume fractions of PS block calculated from the block ratios using 1.05 and 1.11 g cm−3 as densities of PS and P4VP, respectively [19].
