N2 - This study used an integrated approach of investigating both diffusional processes and solution structure in polymer solutions by photophysical means to gain a better understanding of polymerization phenomena. Photophysical techniques are well suited for such a study as they are sensitive to very local interactions and do not result in any permanent change in the system such as those observed with crosslinking reactions or polymerization. Thus, particular diffusion-controlled interactions such as small molecule-small molecule or polymer-polymer interactions may be isolated with photophysical studies. Also, the effect of parameters such as molecular weight, concentration and thermodynamic solvent quality on interpenetration and diffusion-controlled interactions may be easily studied.
