Definition
Macromolecular rotaxane in which rotaxane constitutional units are located exclusively in side chains of the macromolecule.

Note
Typical structure representations of the most common side-chain rotaxane constitutional units are as follows:  where \(\ce{R^{1}}\) and \(\ce{R^{2}}\) are end-groups of a threading component and \(\ce{R}\) is a capping group of a side chain.
