WebIUPAC rules for naming addition polymers. Students should be able to: draw the repeating unit from a monomer structure. Draw the repeating unit from a section of the polymer chain. Draw the structure of the monomer from a section of the polymer. Structure, bonding and reactivity. Alkenes are unsaturated hydrocarbons. WebNote that in the polymer formula, ‘n’ is a variable indicating multiple repetitions and is therefore italicized.Wavy lines, commonly drawn perpendicularly to free bonds and conventionally used to indicate free valences [], are not used in graphical representations of polymers [].Thus, polymer structures use square brackets; partial structures use wavy lines.
