Back Cover : In article number 2000639 by Toshikazu Takata and co‐workers, direct incorporation of a movable rotaxane scaffold into ethylenepropylene‐butadiene monomer (EPDM) rubber, via a post‐crosslinking methodology, using a rotaxane‐type crosslinker containing nitrile N‐oxide functional groups on both axle and wheel components, is achieved. Tensile tests reveal that compared to a network exhibiting conventional covalent crosslinking points, the breaking strength and strain of the formed crosslinked EPDM are improved.
