Abstract
Phenoxyphenylsilane monomers were synthesized and polymerized. The polymers have high refractive indices and excellent UV and thermal stability. Their water and oxygen permeability is lower than commercial phenyl silicone elastomers. They show good compatibility with metal oxide nanoparticles. The polymers of the invention are suitable as LED encapsulant, as light guide material in CMOS image sensors, in OLED devices, lasers and in other optical applications.
