Macromolecular rotaxane in which rotaxane constitutional units are exclusively located within the main macromolecular chain.
Note: Structure representations of basic constitutional units of main-chain macromolecular rotaxanes are as follows: 
where \(\ce{R^{1}}\) and \(\ce{R^{2}}\) are end-groups of a threading component.
