What are silicones?
(N/A) Silicones are a group of organosilicon polymers that have the general empirical formula $(R_2SiO)_n$,where $R$ is an alkyl or aryl group.
They consist of $-(Si(R)_2-O)_n-$ chains in which the alkyl or phenyl groups occupy the remaining bonding positions on each silicon atom.
They are hydrophobic (water-repellent) in nature and possess high thermal stability.
