Patent number: 4542178Abstract: For the thermoplastic processing of polyvinyl alcohol, the processing temperature must be below the decomposition temperature of the polyvinyl alcohol; this is attained by incorporating plasticizers. For preparing a plasticizer-containing granular polyvinyl alcohol wherein the plasticizer is homogeneously distributed, there is used as starting material a granular polyvinyl alcohol consisting substantially of particles having a definite diameter. The plasticizer is incorporated in the presence of a small amount of water insufficient to dissolve the polyvinyl alcohol, and the temperature is adjusted in a definite manner during the mixing operation. Simultaneous presence of fine particles of a high molecular weight organic compound soluble or dispersible in water is advantageous. The plasticizer-containing granular polyvinyl alcohol is suitable for the manufacture of any shaped articles, especially films and sheets.Type: GrantFiled: December 2, 1983Date of Patent: September 17, 1985Assignee: Hoechst AktiengesellschaftInventors: Wolfgang Zimmermann, Albrecht Harreus

Patent number: 4481328Abstract: A pulverulent polymer composition which is readily pourable, has a low tendency to form dust and has good stability on storage is composed of a mixture of a vinyl ester polymer and a small proportion of a hydrophobic silica. The composition is prepared by spray drying an aqueous vinyl ester polymer dispersion in the presence of a hydrophobic silica. The silica is preferably a product from the reaction of a hydrophilic silica with an organochlorosilane. The composition can be redispersed in water and the films produced from such dispersions are transparent; they are suitable for the production of paints, glues and adhesives.Type: GrantFiled: January 15, 1982Date of Patent: November 6, 1984Assignee: Hoechst AktiengesellschaftInventors: Albrecht Harreus, Eduard Kaiser, Detlev Seip, Wolfgang Zimmermann

Patent number: 4453320Abstract: The water content of a material, which tends to either absorb water or to release water, is changed with the aid of a film, which at least partially separates the material from the adjacent space and is impermeable to liquid water but permeable to gaseous water. Polyvinyl alcohol with a particular degree of polymerization and degree of hydrolysis is used as the film material. The film can be mechanically or chemically after-treated. The moistening or de-moistening of the material, which is solid, liquid or gaseous, is effected, utilizing a water vapor pressure gradient, under very mild conditions.Type: GrantFiled: October 16, 1981Date of Patent: June 12, 1984Assignee: Hoechst AktiengesellschaftInventors: Wolfgang Zimmermann, Albrecht Harreus, Richard Gutte
