Effect of Oligomers on the Polymer Diffusion Rate in Poly(butyl methacrylate) Latex Films - Published online 19 September 2000 The influence of oligomer on polymer diffusion in poly(butyl methacrylate) (PBMA) latex films was investigated by the direct energy transfer method. The oligomer was obtained as a byproduct of emulsion polymerization, separated, and added in known amounts to a purified PBMA latex dispersion. Next, latex films were prepared, and in the presence of the oligomeric material, the rate of polymer diffusion in the film was strongly enhanced. The magnitude of the enhancement was fit quantitatively to the Fujita-Doolittle equation, indicating that the oligomers acted like a traditional plasticizer to increase the free volume in the system. All the data were superimposed onto a single master curve./
