  1. 35.1 Condensation polymerisation

    1. 35.1.1Formation of polyesters

      • 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. 35.1.2Formation of polyamides

      • 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. 35.1.3The repeat unit of a condensation polymer

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

    4. 35.1.4Monomer(s) present

      • 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. 35.3.1Poly(alkenes) are chemically inert

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

    2. 35.3.2Some polymers can be degraded by the action

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

    3. 35.3.3Biodegradable polyesters and polyamides

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