thanks a lot. BUt my case is kinda special. it is PEG-PtBA, as u know, PtBA
can be dissolved in almost all solvents except water. therefore, the
solubility property of the block polymer is quite similar to homopolymer.
what I am trying to do is to precipitate PEG in MeOH using ether, while
keeping the block polymer micelles in MeOH. This looks viable but I am not
sure this is the best combination or not in |
