know that an addition polymer is formed by joining up many small molecules called monomers
understand how to draw the repeat unit of an addition polymer, including poly(ethene), poly(propene), poly(chloroethene) and (poly)tetrafluoroethene
understand how to deduce the structure of a monomer from the repeat unit of an addition polymer and vice versa
explain problems in the disposal of addition polymers, including:
know that condensation polymerisation, in which a dicarboxylic acid reacts with a diol, produces a polyester and water
understand how to write the structural and displayed formula of a polyester, showing the repeat unit, given the formulae of the monomers from which it is formed including the reaction of ethanedioic acid and ethanediol:
