  Copolymers, as well as compounds, compositions, articles of manufacture, and methods of making thereof, are disclosed. The copolymers may generally exhibit flexibility properties and may generally have a high refractive index. The copolymers may generally be made by providing a dihydrodisiloxane and an aliphatic vinyl alcohol and combining the dihydrodisiloxane and the aliphatic vinyl alcohol under conditions that allow for hydrogenation of the aliphatic vinyl alcohol and result in coupling of the aliphatic vinyl alcohol to the dihydrodisiloxane to produce a hydroxyl substituted siloxane.
