How can target molecular weight of RAFT reaction depend on CTA instead of Initiator?

I've studied and read the principle of RAFT and its mechanism. By being fragmented and added, the rate of polymerization gets slow under the equilibrium between active and dormant species. But,...

What kind of solvents would be promising if I want to selectively dissolve PS out of PS-PMMA??

Hi, I wonder a specific solvent that can dissolve only PS out of PS-PMMA. Of course, solubility depends on molecular weight of polymer, but if it can be excluded for an ideal situation, I take...
