      abstract     = {We investigated the swelling of a thin film of
                      lamellae-forming poly(styrene-b-butadiene) in cyclohexane
                      vapor. The vapor pressure and thus the degree of swelling of
                      the film are increased in a stepwise manner using a
                      custom-built sample cell. The resulting structural changes
                      during and after each step were followed in situ using
                      time-resolved grazing-incidence small-angle X-ray scattering
                      (GISAXS). During the first step, the lamellar thickness
                      increases strongly, before it decreases again. At the same
                      time, the full width at half-maximum (FWHM) of the diffuse
                      Bragg reflection along the film normal has a sharp maximum.
                      These observations point to the formation of new lamellae.
                      During the subsequent swelling steps, the lamellar thickness
                      overshoots only weakly. The behavior thus resembles
                      qualitatively our previous results on a similar thin film
                      during swelling in saturated vapor of cyclohexane; however,
                      it deviates from earlier theoretical predictions. We propose
                      a theory that is quantitatively correct for the description
                      of the dependence of the lamellar thickness on the polymer
                      volume fraction in the late stage of the swelling steps.},
