MCQ
Which of the following monomers are unsuitable for condensation polymerization?
- AHydroxy acids.
- BButane$-$dioic acid and glycol.
- CDiamines and dicarboxylic acids.
- ✓Propanoic acid and ethanol.
✓
Answer
Correct option: D.
Propanoic acid and ethanol.
Propanoic acid and ethanol, both are monofunctional monomers $\mathrm{CH} 3-\mathrm{CH}_2-\mathrm{OH}, \mathrm{CH}_3-\mathrm{CH}_2 \mathrm{COOH}$ which are not suitable for a polycondensation reaction to take place because once they combine by condensation polemerisation further polymerisation is not possible.
