6.2.3: Polyesters and polyamides

#6.2.3a

condensation polymerisation to form:

(i) polyesters (ii) polyamides

Formation from carboxylic acids/dicarboxylic acids (or respective acyl chlorides) and from alcohols/diols or amines/diamines. Learners will not be expected to recall the structures of synthetic polyesters and polyamides or their monomers.

#6.2.3b

the acid and base hydrolysis of:

(i) the ester groups in polyesters (ii) the amide groups in polyamides

#6.2.3c

prediction from addition and condensation polymerisation of:

(i) the repeat unit from a given monomer(s) (ii) the monomer(s) required for a given section of a polymer molecule (iii) the type of polymerisation.
