  1. 35.1 Condensation polymerisation

    1. • Describe the formation of polyesters:: (a) the reaction between a diol and a dicarboxylic acid or dioyl chloride; (b) the reaction of a hydroxycarboxylic acid

    2. • Describe the formation of polyamides:: (a) the reaction between a diamine and a dicarboxylic acid or dioyl chloride; (b) the reaction of an aminocarboxylic acid; (c) the reaction between amino acids

    3. • Deduce the repeat unit of a condensation polymer obtained from a given monomer or pair of monomers

    4. • Identify the monomer(s) present in a given section of a condensation polymer molecule

  2. 35.2 Predicting the type of polymerisation

    1. 35.2.1The type of polymerisation reaction

      • Predict the type of polymerisation reaction for a given monomer or pair of monomers

    2. 35.2.2The type of polymerisation reaction

      • Deduce the type of polymerisation reaction which produces a given section of a polymer molecule

  3. 35.3 Degradable polymers

    1. • Recognise that poly(alkenes) are chemically inert and can therefore be difficult to biodegrade

    2. • Recognise that some polymers can be degraded by the action of light

    3. • Recognise that polyesters and polyamides are biodegradable by acidic and alkaline hydrolysis
