Condensation polymerisation
Joining of monomers which forms a water molecule at the end
How can polyesters be formed?
From one monomer with both carboxylic acid and alcohol group From two monomers - a dicarboxylic acid and a diol
How can polyamides be formed?
From one monomer with a carboxylic acid/acyl chloride group and amine group From two monomers - dicarboxylic acid/acyl chloride and a diamine
How can polyesters and polyamides be hydrolysed?
Using hot aqueous sodium hydroxide Using hot aqueous acid
