Abstract

Kinetics of phase separation of PBO in methane sulfonic acid are examined by time-resolved small angle light scattering. Thin films of polymer solutions are spincoated on microscope slides and observed in a controlled environment light scattering cell. These solutions appear to undergo spinodal decomposition, following Cahn- Hilliard type phase separation kinetics upon exposure to water, leading to an exponential increase in the scattered light intensity at short times.
