A modified silicon-containing material, a method of making it, a cured article formed from such material, and the provision of its utility in various applications. A polymeric material comprising a bicyclo (2,2,1) ring system, most preferably a constrained bicyclic bridged structure such as a norbornyl group suspended on a siloxane backbone. Cross-linked bicyclic containing materials can exhibit good refractive index, transparency, gas permeability, and / or other properties and are suitable for use in various applications. 【Selection chart】 None |
