Abstract: Polyacrylonitrile articles, such as filaments, tapes and films, having high tensile strength and modulus, and prepared by adding to a solution of polyacrilontrile with a molecular weight above 3 x 10 5 , pref. above 5 x 10 5 , a minor amount of a bivalent metal compound, converting the solution into a solvent containing article, cooling this article to form a gelarticle, removing from this gel the solvent and metal compound, and stretching the resulting article at increased temperature.With this process filaments with a tensile strength above 1.2 GPa and a modulus above 16 GPa can be obtained.

Abstract: High modulus and high strength articles of polyvinyl-alcohol are obtained by thermoreversible gelation of a 5-50 wt.% solution of a polyvinylalcohol with an M w of 2.5 × 10⁴ to 5 × 10⁵ in water, followed by solvent removal and high stretching.Pref. gelation is obtained by cooling to a temperature of at least 40 ◊C below the gelation temperature.With this process low costs of solvent removal and regeneration are obtained.
