ABSTRACT:
A non-destructive method for determining the degree of cure of a polymer, e.g., a polymer film, is based upon measuring the degree of free space rotation of a fluorophore added to the polymer system through fluorescent measurements of the fluorophore. The results can be used to control, on-line, the polymerization of the polymer.
