， 大侠帮个忙， 看有什么文献有过报道
还有PCL的 repeat unit 长度问题。

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 |

发帖数: 2145 | 3 Thanks for your infos, especially the monomers that can be polymerized via
atrp.
My difficulty here is that the first block is non-soluble in water, this is
fixed. I was just wondering how can I run aqueous ATRP with the oil soluble
macroinitiator.
For example, the first bloack is PnBA or PtBA.
Maybe I can use methanol as solvent and at higher temperature, it might be a
good solvent for both PtBA and PSS?
Any comments?
Thanks a lot
