How many of the following polymers act as elastomers (rubbers) due to the presence of weak van der W — Polymers Chemistry Question
Question
How many of the following polymers act as elastomers (rubbers) due to the presence of weak van der Waals forces between their uncoiled chains? Buna-S, Neoprene, Terylene, Polyacrylonitrile (PAN), Buna-N, Natural rubber.
Answer: 4
💡 Solution & Explanation
Elastomers have weak intermolecular forces. Buna-S, Neoprene, Buna-N, and Natural rubber are elastomers. Terylene and PAN (Orlon) are classified as fibres due to stronger intermolecular forces. Therefore, the count is 4.
