Answer: Resistance to oil, weather, and ozone.
- A Resistance to oil, weather, and ozone
- B High electrical conductivity according to standard textbooks
- C Transparency in general practice
- D Biodegradability as frequently described
Correct answer: A. Resistance to oil, weather, and ozone
Explanation: Neoprene is resistant to oil, ozone, and weathering, making it valuable for wetsuits, hoses, and cables.
Addition polymerisation simply links monomers containing a double bond with nothing left over, while condensation polymerisation joins two different monomers through a reaction (often forming an ester or amide bond) that releases a small molecule like water at each step.
Concept context
Large molecules made of repeating monomer units. Covers addition and condensation polymerisation, natural and synthetic polymers (nylon, PVC, Bakelite, natural rubber), and their real-world industrial applications.
