|Abstract: ||The use of fluorescence spectroscopy in the study of associative phenomena is
illustrated . The use of standard global of and global compartmental analysis in a
number of complex systems is clearly shown. Association between detergent
molecules and between detergents and polymers was analysed and the different
parameters characterising such an interaction evaluated. Associative phenomena in
covalent polymers such as dipole-dipole interactions in halato-telechelic polymers
and in syndiotactic polymethylmethacrylate were investigated. The rate constants
of inter and intramolecular interactions in halato-telechelic polymer were
determined through a systematic analysis of the different interactions using global
tricompartmental analysis of fluorescence decays combined with a scanning
technique to estimate the rate constants. Fluorescence polarization and changes in
fluorescence decay times in the temperature range of gelation reveal a stepwise
mechanism in the gelation of s-PMMA.|
