Abstract
Polymeric structure involving a first polymer having a linear segment and a second polymer having a macrocyle which is threaded onto said linear segment to form a rotaxane complex. The rotaxane complex is capable of reversibly dissociating back into the individual polymers under the influence of an external factor, such as temperature and/or solvent exposure.
