Hydrogen‐bonded duplexes of incompatible polystyrene and poly(ethylene glycol) chains have been prepared that show microphase separation (see picture). Differential scanning calorimetric studies of the phase transitions for these copolymers show that they behave like typical covalently bonded diblock copolymers at temperatures below 170 °C.
