Melt spinning of a poly-(ethylene-octene)-copolymer with elastomeric properties shows that this material is also a melt spinnable polymer. The mechanical properties obtained for the spun fibers are similar to those of an elastance yarn and are only influenced by variation of the spinning conditions. This however is not acceptable for textile applications, due to the low-melting temperature (60℃) of this polymer. It is expected that by blending the basic polymer with an appropriate polyolefin copolymer, which possesses a high degree of crystallinity and a higher melting point, it is possible to raise the softening temperature. The expectation is that in a defined concentration range of the blend components co-continuous phase structures occur, which should result in distinctive advantages for the fracture mechanics of the melt spun fibers.
