7. The nomenclature adopted by IUPAC rests upon selection of preferred
constitutional repeating
units [
5
] from which the polymer is a multiple. The unit is named wherever possible according to
the definitive rules for nomenclature of organic chemistry [
24
]. For single-stranded polymers this
unit is a bivalent group. An example is a polymer with oxy(1-fluoroethylene) constitutional
repeat unit:
O
