A
macromolecule that comprises
constitutional units connected in such a way that adjacent constitutional units are joined to each other through more than four atoms, more than two on at least one side of each
constitutional unit.
Note:
A macromolecule that comprises constitutional units joined to each other through

atoms on at least one side of each
constitutional unit is termed an
n-strand macromolecule, e.g. three-strand macromolecule. If an ambiguity exists in defining

, the highest possible number is selected.
