In situ synthesis of PAA-b-PSt nano-assemblies via dispersion RAFT polymerization: effects of PEG in the medium

A facile and efficient approach was developed to manipulate BCP assemblies in PISA by introduction of PEG in the medium. Both the amount and the molecular weight of PEG have significant effects on PAA-b-PSt micelles. More importantly, vesicles with more uniform size can be easily prepared and tuned via the addition of PEG.
