Condensation polymers
Chemistry · Secondary 4 · Medium · Condensation polymers
A polyester is formed by the condensation polymerisation of a diol and a dicarboxylic acid.
The polymer is hydrolysed by heating with dilute acid to form its monomers. Aqueous sodium hydroxide is then added to the mixture of monomers.
What are the products after adding sodium hydroxide?

What are the products after adding sodium hydroxide?
- Only the original polyester is re-formed.
- A diol and a dicarboxylic acid.
- A diol and sodium salts of a dicarboxylic acid.
- Only sodium carbonate and water.
