Question

What are Silicones?

Answer 1

Silicones

• They are a group of organosilicon polymers, which have ${\text{(-R}}_2\text{SiO-})$ as a repeating unit.
• The starting materials used to make silicones are aryl or alkyl-substituted silicon chlorides,${\mathrm{R}}_{\mathrm{n}}{\mathrm{SiCl}}_{(4–\mathrm{n})}$, where $\text{R}$ is an alkyl or aryl group.
• They are hydrophobic (water repellant) in nature.
• 

Uses of silicones

• They are used as sealants, electrical insulators, greases, and fabric waterproofing.
• They are also used in surgical and cosmetic plants due to their biocompatibility.
