ABSTRACTKinetics 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.

Small Angle Light Scattering

A time-resolved small-angle light scattering apparatus equipped with azimuthal integration by means of a conical lens or software analysis of scattering patterns detected with a CCD camera was developed. Averaging allows a significant reduction of the signal-to-noise ratio of scattered light and makes this technique suitable for investigation of phase separation kinetics. Examples of applications to time evolution of phase separation in concentrated statistical copolymer solutions and dissolution of phase-separated domains in polymer blends are given.
