这个还是比较容易的,用ABIN作为诱发剂就可以合成的,我看到有用ABIN合成三元的都可以
但是有个问题,前一个单体容易自聚,从而导致合成不是很完全

祝顺利~

We want to get the regular copolymer, not the random copolymer. Do you think it is easy to get that without ATRP?

ATRP也可以的,你查查类似的合成条件吧

Of coz, PS should be the first block. and the method of ATRP is mature, you can find it easily.

for the second block, I think there is some issue to be noted:
1, there are two nitrogen atoms. So in my opinion, strong chelating agent should be used like Me6TRAN.
2, I do not know Cl- will affect the monomer's polymerization, because the mechanism of metal like Cu is coupling with Cl- to inhibit the radical.
3. you need to keep the second monomer positive charged only as which have aromatic properties and keep the monomer active.

for accurate synthesis, you need to refer to web of science, or SciFinder, you can search by structure or reaction.

I did not search that. if not find in literature, you need to try, there may be other problem to be encountered.

Good luck!
