Abstract
A method and apparatus (10) for detection of the degree of cure of a polymer in situ and non-invasively. The method and apparatus uses a solvatochromic probe molecule which upon curing produces a shift in the fluorescence emission spectrum as compared to a liquid polymerizable composition. The method and apparatus is particularly adapted for poly(vinyl) polymers. Preferred solvatochromic probe molecules are oxazones and pyrene.
