Altogether, our visual and rheological evaluation confirms a high dependency of the thermogel properties on polymer composition and architecture in the case of the pPheOzi-based system. -% aqueous solutions of pPheOzi-copolymer variants (A: P_T, P_D, P_G and P_S; B: P_pMeOx and P_PEG) after incubation at 5 °C. Dissolution of the gels is followed by temperature-dependent rheology measurements conducted at 1.0% strain and an angular frequency of 10 rad/s using an increment rate of 0.5 °C/min. Liquefaction of the gels is indicated by drastic drop in complex viscosity.
