Desorption coefficients, D-d of pyrene (P) desorbing from the swelling PMMA glass prior to dissolution were measured and found to be 8.3 x 10(-8) and 1.3 x 10(-5) cm(2) s(-1) in short and long time regions, respectively.eninfo:eu-repo/semantics/closedAccessTransient fluorescence techniqueLow-density polyethyleneDissolutionDiffusionFilmsColloidsInterferometryLuminescenceDispersionsMorphologyDesorptionSwellingPolymeric glassFluorescenceArticle921269273Q2WOS:0002286989000452-s2.0-1594439615110.1016/j.matchemphys.2005.01.029Q1
