Abstract: We describe polymer diffusion measurements in a poly(vinyl acetate) copolymer latex film by fluorescence decay measurements of nonradiative energy transfer (FRET). The base monomer is a 4:1 weight ratio copolymer of vinyl acetate and butyl acrylate P(VAc−BA) with a glass transition temperature of ca. 12 °C. P(VAc−BA) latex particles labeled with phenanthrene (Phe) as the donor and with 4-(N,N-dimethylamino)benzophenone (NBen) as the acceptor were prepared by semicontinuous emulsion polymerization. Latex films were cast from a 1:1 mixture of Phe- and NBen-labeled latex samples. First, a series of films containing NBen-labeled latex samples with different NBen levels were annealed at 45 °C, showing that NBen levels have no influence on the rate of polymer diffusion in P(VAc−BA) latex films. From the fully mixed solvent-cast films, the characteristic distance for energy transfer between Phe and NBen (the Forster radius R0) was obtained as 2.44 nm. Then, polymer diffusion was monitored as a function of anneal...

TL;DR: Using thermal volatilization analysis with differential condensation of volatile products, with film samples on flat-bottomed silica glass reaction tubes to permit measurements of UV spectra of partly degraded polymer, the thermal stability, the types of volatile product and the development of conjugation in the involatile residue have been compared for poly(vinyl chloride, polychloroprene, polyvinyl acetate) and vinyl acetate/ethylene copolymers as discussed by the authors.
