摘要
A thermoplastic, segmented, linear copolyetherester elastomer of at least 70 weight percent soft segments, derived from poly(alkylene oxide) glycols and terephthalic acid, and hard segments constituting 10-30% of the elastomer and being 95 to 100% poly(1,3-propylene terephthalate). Melt-spun and drawn fibers of the elastomer have superior elastic and set properties versus comparable fibers made from such elastomers having hard segments of poly(ethylene terephthalate) or of poly(1,4-butylene terephthalate).
