Polymer diffusion across interfaces at room temperature (21ΠC) was analyzed by direct nonradiative energy transfer (DET) in labeled latex films. Two model latex polymers were examined: poly(butyl methacrylate) [PBMA, M w Γ 3.5 1 10 4 , T g (dry) Γ 21ΠC] and a copolymer of 2-ethylhexyl methacrylate w
## Abstract We describe nonβradiative energyβtransfer experiments to measure the rates of polymer interdiffusion in P(MMAβ__co__βBA) latex films formed in the presence of poly(vinyl alcohol) (PVOH). PVOH had relatively little effect on the initial efficiency of energy transfer, even when the amount
