Small‐angle X‐ray scattering using synchrotron radiation at pressures up to 700 MPa has been performed on triblock‐copolymer gels, polystyrene‐rubber‐polystyrene with poly(ethylene/butylene) as the rubber mid‐blocks. A 2‐stage pressure behaviour could be verified by comparison of the experimental data with the Tait‐equation and a model of pressure screening.
