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.
