Characterization of Poly(Ethylene Oxide) Drawn by Solid State Extrusion.

Abstract

Samples of coextruded poly(ethylene oxide) (PEO), drawn to ratios of up to 31, were prepared and studied using techniques of x-ray diffraction, birefringence, differential scanning calorimetry and dynamic mechanical analysis. The amorphous component was found to orient first on draw, this occurring up to a draw ratio of 3 to 4. The crystalline component oriented as the draw ratio was increased from 3 to 12, as seen by the crystalline orientation function fc which increased in that interval from 0.28 to .943. A value of .975 was obtained for fc at a draw ratio of 28. Additional keywords: computations. (Author)
