Fully aromatic synthetic fibers spun from a solution of crystalline polìmero lìquido,Process for the preparation of such fibers and material of synthetic fibres wholly aromatic

摘要

Are described fully aromatic synthetic fibers spun from solutions of liquid crystalline polymer.With the size of crystal plan (110) of not more than 50 and and ionic substance content of not more than 1.0% by weight.These fibers have low ionic substance content, while maintaining high heat resistance inherent and high Young's modulus.It is particularly useful for electric and electronic parts.
