Abstract

We reconsider the initial growth process of the unstable concentration fluctuations when a polymer blend of A and B chains (NA = NB) is rapidly quenched into the unstable region. We correct an earlier result and now predict (i) that the unstable wavelength 2π/? is on the order of R0 (ideal chain radius) for the case of strong segregation, and (ii) the corresponding growth rate is proportional to the melt reptation diffusion constant. These results are consistant with the phase separation kinetics observed in polystyrene–poly(vinyl methyl ether) blends by Nishi, Wang, and Kwei.
