I am really confused.
If a carboxylic acid + an alcohol --> an ester + water, why is this not condensation polymerisation?
Sorry if this is a stupid question, but I'm just confused what the difference is.

Polymerisation is where there are many monomers joining to form a long chain in this case only one of each of the reactants joins to form one ester. Condensation polymerisation would be between a dicarboxylic acid (-COOH group both ends) and a diol (-OH group both ends) - as there’s always a spare -OH group and -COOH group more molecules can react with these groups to join the chain and form another ester bond.

Polyesters can also form from a single monomer that has a -COOH group one end and a -OH group the other.

Good reminder of what polymerisation means - https://www.google.co.uk/url?sa=t&rc...XqDcO5aK72a_9j

Thank you for your reply!
So in condensation polymerisation, there's the bracket and bonds extending out at the ends because it can make a longer chain, as opposed to just creating a molecule? (did that make sense?)

Yeah there would be many repeating units
