Paper Abstract

Films with various thicknesses were formed from pyrene labeled poly (methyl methacrylate) (PMMA) high Tg latex particles, sterically stabilized by poly isobutylene. Annealing of films were performed above Tg at elevated temperatures up to 270 degree(s)C for 30 min time intervals. UV- Visible technique was used for monitoring of film formation and dissolution. Absorption of chloroform molecules into the annealed latex film was followed by diffusion of PMMA chains into solvent reservoir. Diffusion coefficients of PMMA chains were measured and found to be in between 2.6 x10- 9 cm2 s-1 to 9.7 x 10-13 cm2 s-1 for the latex films in various thicknesses. It was observed that thicker films dissolved much faster than the thinner films.
