Swelling kinetics (left hand axis: black curves) of ~40 nm thick PS-PVP films (a) under chloroform vapor with partial vapor pressure of 50%, and (b) under toluene vapor with p/p0 of 100% at stepwise increasing of Tv and Ts (right hand axis: green curves and red curves, correspondingly). Temperature set Tv/Ts are the following: (A,A’)—20 °C/30 °C, (B,B’) —25 °C/30 °C, (C,C’) —29 °C/30 °C, (D,D’) —29 °C/35 °C, E—29 °C/40 °C, E’—34 °C/40 °C, F’—34 °C/35 °C, (G,G’) —39 °C/40 °C.
