Novel Cross-Linker Capable of Endowing Polymer with Toughness
Network polymers having rotaxane structures at the cross-link points are characterized by the movable polymer chains at the crosslink points and thereby show unique properties and functions that have never been achieved with any physically or chemically crosslinked polymer.1-3 The movable polymer chain in network polymers make possible an equalization of tension for external stimuli or stress to produce high swelling ability for solvents, high elasticity, and high stress-releasing ability.We have hitherto prepared a various rotaxane-cross-linked polymers (RCPs) showing recyclable and stimuli-responsible nature.In this paper, we would like to discuss the synthesis of roaxane cross-linkers having two vinyl groups on the axle and wheel components, with which the corresponding RCPs obtained by the radical polymerizations of common monomers displayed toughness more than cross-linked polymers obtained with a typical chemical cross-linker (CCPs).
