Abstract

A polymer material comprising a constraint bicyclic bridged structure such as bicyclo(2,2,1) ring system, most preferably a norbornyl group, pendant to a siloxane backbone. The bridged bicyclic-containing materials can exhibit good refractive index, transparency, gas permeability, and/or other properties making them suitable for use in a variety of applications.
