Macromonomer purification strategy for well-defined polymer amphiphiles incorporating poly(ethylene glycol) monomethacrylate
Commercial hydroxy-terminated poly(ethylene glycol) monomethacrylates (PEG-MAs) contain poly(ethylene glycol) dimethacrylate, which leads to unfavorable gel formation on polymerization. Here, hydroxy-terminated PEG-MA is readily isolated using a dimethylsilyl resin chlorinated with 1,3-dichloro-5,5-dimethylhydantoin.
