POLYROTAXANE FIBER

摘要

PROBLEM TO BE SOLVED: To provide a polyrotaxane fiber capable of achieving its own high elasticity and high mechanical strength without mutually crosslinking cyclic molecules or crosslinking a cyclic molecule with other polymers. SOLUTION: The polyrotaxane fiber is composed of a polyrotaxane which comprises: a cyclodextrin-based cyclic molecule; a polyethylene glycol skeweredly included in the cyclic molecule; and both-terminated blocking groups of the polyethylene glycol. In the fiber, the cyclodextrin-based cyclic molecule has at least a crystal structure having plane indexes designated as (110) and (210). The fiber is 8 (cN/dtex)1/2or greater in toughness in the fiber extension direction. COPYRIGHT: (C)2011,JPO&INPIT
