Which one of the following is not used as an initiator in ionic polymerisation?
Options
- ANaNH ₂
- BSnCl ₂
- CAlCl ₃
- D( C ₆ H ₅ CO )₂ O ₂
Correct answer
D. ( C ₆ H ₅ CO )₂ O ₂
Step-by-step solution
In ionic polymerisation ions/ion pairs have ends with ionic center ( C ₆ H ₅ CO )₂ O ₂ is a covalent compound and will not give any ionic center for chain initiation, thus can not be used as an initiator in ionic polymerisation.
