Add syllabus

#C4.2.1

recall the basic principles of addition polymerisation by reference to the functional group in the monomer and the repeating units in the polymer

#C4.2.2

deduce the structure of an addition polymer from a simple monomer with a double bond and vice versa

#C4.2.3

explain the basic principles of condensation polymerisation by reference to the functional groups of the monomers, the minimum number of functional groups within a monomer, the number of repeating units in the polymer, and simultaneous formation of a small molecule

Learners are not expected to recall the formulae of dicarboxylic acid, diamine and diol monomers

#C4.2.4

recall that DNA is a polymer made from four different monomers called nucleotides and that other important naturally-occurring polymers are based on sugars and amino-acids
