摘　　要：We present here a novel strategy for the chemical recycling of bio-based poly(ethylene furanoate)s(PEF)to value-added high-performance bio-based poly(ethylene-co-isosorbide furanoate)(PEIF)copolyesters by the combination of cyclodepolymerization method with rapid cascade polycondensation-coupling ring-opening polymerization(PROP).The solution cyclodepolymerization of commercially available PEF affords cyclic oligo(ethylene 2,5-furandicarboxylate)s(COEFs),and the effects of reaction conditions on the yield of COEFs were studied.PEIF copolyesters with different isosorbide(IS)contents were synthesized via the cascade PROP of COEFs with IS,which show significant enhanced glass transition temperature.By melt spinning,PEIF fibers with different orientation factors were prepared,with excellent thermal stability and mechanical performance.The obtained PEIF fibers can lift a weight∼25000 times higher than its weight.The PEIF fibers are stable under ambient conditions but are biodegradable following the“surface erosion”mechanism.These sustainable value-added biodegradable PEIF fibers offer a solution to the environmentally friendly fibers.
