Table 1.
Characterizations of the POEG15 Macro-RAFT agent, POEG15-b-PFTS6 and POEG15-b-PFTS16 block copolymers.
| Block compolymer | Monomer conversiona | Hydrophilic/Hydroph obic ratiob | Mna (NMR) | Mnc (GPC) | Mwc (GPC) | Mw/Mnc (GPC) |
|---|---|---|---|---|---|---|
| POEG15 | 75 | - | 7500 | 7130 | 8140 | 1.14 |
| POEG15-b-PFTS6 | 75 | 7500/2844 | 10700 | 9160 | 10260 | 1.12 |
| POEG15-b-PFTS16 | 70 | 7500/7584 | 15500 | 13700 | 17600 | 1.30 |
Notes:
a
Calculated by NMR results.
b
The block molecular weight ratio of OEG/FTS in polymers.
c
Measured by GPC with THF as the eluent, and the molecular weights and their distribution were calculated with polystyrene standards.
