Direct enhancement of intercomponent interactions in polyrotaxane and its pronounced effects on glass state properties

Strong interactions between the host cyclodextrin and the threading guest polymer were introduced by selective modifications to the polymer of a polybutadine-based polyrotaxane. The changes in the intercomponent interactions influenced the mobility of the threading polymer that was confined in the g...

Description
Summary:Strong interactions between the host cyclodextrin and the threading guest polymer were introduced by selective modifications to the polymer of a polybutadine-based polyrotaxane. The changes in the intercomponent interactions influenced the mobility of the threading polymer that was confined in the glassy host framework, resulting in different mechanical properties. Intercomponent interactions in polyrotaxane glass influenced the mobility of the threading polymer confined in the glassy host framework, resulting in markedly different mechanical properties.
