Abstract
Strong fibers of poly(ethylene oxide) result from crystallization of the polymer of molecular weight of at least about 500,000 in a shear flow field. Using solutions of a polymer with a molecular weight greater than about 1,000,000, fibers with a tensile strength and tensile modulus of at least 0.1 and 0.5 GPa, respectively, can be readily obtained. Crystallization from a xylene solution within the range from about 35.degree. to about 45.degree. C. is particularly effective.
