Answer 2

Answer:

When making polysiloxane, copper is utilised as a catalyst in the form of CuO.

Explanation :

• There have been many different silicon-containing polymers created in the past.
• The silicones or polysiloxanes category of these polymers is the most significant one.
• Polysiloxanes are thought of as hybrid inorganic-organic compounds. Si and O atoms make up the primary chain, whereas alkyl groups make up the side groups.
• These polymers are present in resins, elastomers, and silicone oils. Ring-opening polymerization is used to create the linear polymers known as silicone oils.
• They can be utilised as heat transfer fluids since they are thermally stable.
• Elastomer silicones are cross-linked polysiloxanes that can be utilised in food containers and automobiles.
• The high cross linking density of silicone resins, on the other hand, contributes to their excellent thermal stability.
• Because of this, they are used to colour outdoor surfaces and are also widely utilised as water repellants.
