The pMeOx-b-pPheOzi-b-pMeOx triblock P_pMeOx displays an almost identical rheological profile compared to P_T but exhibits a slightly reduced gel strength (GP_pMeOx' ≈ 21 kPa) (Fig. ). It can therefore be assumed that the synthesis protocol (sequential monomer addition vs. coupling procedure) does not have a major influence on the reversible thermogelation. Hence, alterations of the rheological profile of P_PEG can be attributed to the variation of the hydrophilic blocks and are not primarily a result of the coupling procedure. Interestingly, the 20 wt.-% P_PEG sample displays slightly higher gel strength (GP_PEG' ≈ 68 kPa) and similar gel-sol transition temperature compared to its pMeOx-based counterparts P_pMeOx and P_T. Previous variations of the pMeOx blocks using EtOx or MeOzi repeat units were shown to reduce both gel strength and the persistence against temperature. The PEG variant is therefore the first alteration of the hydrophilic units of pPheOzi- based triblocks that does not lead to a weakening of the resulting thermogels but shows comparable performance to the "original" pMeOx-b-pPheOzi-b-pMeOx triblock. In addition, it exhibits a concentration-dependent gel strength (Sup. Fig. ), as was previously shown for the pMeOx-b-pPheOzi-b-pMeOx triblock .
