摘要

The segmented block copoly(ether ester)s were swollen by tetrahydrofuran (THF) at 60℃ and formedfibers by gel-drawing. The morphology and properties of these fibers were investigated by optical and electron microscopes

X-ray diffraction

DSC and an Instron test machine. The band structure morphology was observed in the gel-drawing fibers. The molecular chains were highly oriented as proved by X-ray diffraction data. The results indicated that the gel-drawing fibers have much better mechanical properties than those obtained otherwise.The tensile strength and elastic modulus were found to be 280 MPa and 802 MPa

repsectively.The mechanism of the gel-drawing process was also discussed.
