Abstract

PURPOSE: To obtain the title tough molded article of uniform composition with ease, by heat-treating an article molded from an aqueous dispersion containing (A) polyvinyl alcohol and (B) a gelatinizer.
CONSTITUTION: An aqueous dispersion consisting mainly of (A) polyvinyl alcohol, preferably having a suponification degree ≥97 mol% and substantially insoluble in cold water, and (B) a gelatinizer, preferably a titanium compound, is molded by casting into a mold. The molded article is then gelatinized by heating preferably at 90W95°C for 5W30 min.
EFFECT: Improve strength, elasticity, shape retention, and resistance to hot water.
USE: Artificial feed, regenerator, cushioning materials of berths, contact lenses, etc
