Notes:
A variety of polyorganosiloxanes containing dimethyl, diphenyl, and methylphenyl substituents were studied to determine transparency and optical radiation hardness. Siloxanes show superior optical radiation hardness when compared to optical thermoplastics such as PMMA. Transparency is diminished in polymers containing diphenyl units. This is attributed to the inability to remove traces of the crystalline monomer. Methylphenyl polymers are highly transparent. The maximum attainable refractive index in transparent systems is 1.53.
