Abstract
We study numerically the effects of thermal fluctuations on phase separation in polymer-solvent mixtures, when the polymer-rich region forms a gel. We find that thermal noise restores rapid domain growth through a Brownian-coalescence mechanism. This constitutes a possible explanation of the experimental observation (Bansil, R., Lal, J. and Carvalho, B.L. (1992). Effects of gelation on spinodal decomposition kinetics in gelatin. Polymer, 33, 2961) that deep quenches are necessary for the formation of microstructures in phase-separating polymer-solvent mixtures.
