Abstract
Polymer compositions having a styrene-derived backbone chain and having pendant side chains containing a nitrone functional group undergo changes in refractive index upon exposure to actinic radiation. Waveguides are 'written' in films containing such polymers by exposing predetermined areas to sufficient radiation to change the refractive index.
