| 摘要 |
A thermoplastic, segmented, copolyetherester elastomer having soft segments derived from poly(alkylene oxide) glycols and bibenzoic acid, and hard segments constituting 10-17 weight percent of the elastomer and being 95 to 100% poly(1,3-propylenebibenzoate). Melt-spun fibers of the elastomer have significantly superior elastic and set properties and are less stiff than similar elastomeric fibers having the same soft segments but with hard segments of poly(ethylenebibenzoate), poly(1,4-butylenebibenzoate) or poly(1,6-hexylenebibenzoate).
