ABSTRACT:
Flexible composites, such as those useful as light pipes, may be effectively cured by reactions upon copolymerized alkoxysilane functionality. Improvements in the optical properties of the uncured and cured systems are found when the alkoxysilane monomer is stabilized during preparation, storage, and copolymerization with low levels of non-aromatic stable free radicals or stable free-radical precursors, such as nitroxides.
