Abstract We used initiation solutions of DBU and different thiols for the controlled ring‐opening homo‐ and copolymerization of ethoxy ethyl thio glycidyl ether (EETGE) and allyl thio glycidyl ether (ATGE) to side‐chain multifunctional polysulfides. Optimized preparation conditions allow the syntheses of monomodal homopolysulfides and monomodal polysulfide‐ block ‐mPEG copolymers. Furthermore, copolymers of EETGE and mPEG are firstly synthesized, characterized, and finally deprotected to yield intact poly(thio glycidol)‐ block ‐poly(ethylene glycol) copolymers. These amphiphiles are suitable to form particles in aqueous solutions as confirmed by DLS and cryo‐SEM measurements.
