Outline of Final Research Achievements

In this study, rotaxnae cross-linkers (RCs) with definite structure were provided as the ideal models for rotaxane cross-linked polymers (RCPs) showing prominent properties such as stress relaxation and high tensile, to reveal how the chemical structure of rotaxane linkage affects the mechanicsl properties of RCP.[2]Rotaxane and macromolecular [2]rotaxane were synthesized as the structure-definite RCs and applied to radical polymerizations of vinyl monomers, resulting in the successful syntheses of RCPs. It was revealed that the mechanical properties of resulting RCPs with definite structure at cross-linked points, showing both flexibility and toughness, are determined by the mobility of the components, which is derived from bulkiness of axle chain, in the rotaxnae structure.
