Abstract

Time-resolved small-angle neutron scattering (SANS) experiments were performed on the self-assembling process of a binary mixture of deuterated polybutadiene and protonated polybutadiene at the critical composition. Specimens held in the single-phase state at an initial temperature (Ti) were quenched to a point inside the spinodal phase boundary at a final temperature (Tf) to induce phase separation via spinodal decomposition (SD). The effect of the thermal concentration fluctuations on the SD was examined by changing Ti for a fixed Tf. The wave number and temperature dependence of Onsager kinetic coefficient were also investigated as a function of Ti and Tf.

  18. The time t should be the one at a sufficiently long time in the early stage so that the scattering arising from the concentration fluctuations developed by SD is significantly larger than that from the initial concentration fluctuatations existing before SD.
