| Popis: | Polymer interdiffusion between latex particles during film formation is studied using the fluorescence technique of nonradiative energy transfer (NET). Model emulsion polymers of poly(butyl methacrylate) and poly(amyl methacrylate), labeled with the energy transfer pair of 1-naphthylethyl methacrylate or 9-anthryl methacrylate, are investigated. The effects of particle size, polymer T g , and polymer compatibility on the rate and extent of interparticle diffusion are measured. In addition, the time dependence of TEM images during the final stage of film formation augments the conceptual picture of interdiffusion |
