Afterward, we additionally showed that with a change from ATRP to SET-LRP it is possible to change from the addition of only 6-7 PtBAMA units per arm (ATRP) to longer chains of up to 41 repeat units (SET-LRP)in a well-controlled manner. For all block copolymers, deprotection PDha was possible in a one-pot reaction using TFA and the resulting double hydrophilic block copolymers revealed interesting solution properties, which resulted in an increased aggregation tendency at low pH values, as indicated by a combination of DLS, AFM, potentiometric titrations, and ζ-Potential measurements.
