Abstract

Copolyetheresters are us,ed as an engineering thermoplastic elastomer due to their excellent mechanical properties, thermooxidative stability up to high temperatures and a good resistance against many chemicals. However, fibers made from the copolyetheresters exhibited elastic recovery of about 80-85％ after being stretched 200％, while spandex fibers usually showed 90-95％ recovery. (omitted)
