PNIPMAM - a thermoresponsive polymer under high pressure: Role of the hydrophobic effect for the phase separation
We wish to investigate the thermoresponsive polymer poly(N-isopropylmethacrylamide) (PNIPMAM) in aqueous solution across the coexistence line in the pressure-temperature frame. In this polymer, the hydrophobic interaction between the alkyl groups is important. Pressure allows to vary the hydrophobic effect, and pressure scans at low and at high pressure will give information about the chain conformation and aggregation behavior. Rapid pressure jumps across the coexistence line along with kinetic SANS will give information about the collapse and aggregation behavior with ~100 ms time resolution.
