Abstract
This invention pertains to pristine phenylpropylalkylsiloxanes consisting of mixtures of linear and cyclic siloxanes containing the structure ##STR1## and a method for their preparation. The pristine phenylpropylalkylsiloxanes of the instant invention contain no detectable silicon hydride (--SiH), free organics (--C.dbd.C--) or free inorganics. Additionally, the pristine phenylpropylalkylsiloxanes of the instant invention are high refractive index organosilicone polymers.
