  • Patent number: 4542178
    Abstract: 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.

  • Patent number: 4481328
    Abstract: 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.

  • Patent number: 4453320
    Abstract: 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.

  • Patent number: 4369281
    Abstract: A molding composition on the basis of polyvinyl alcohol substantially consists of a partially solvolyzed graft copolymer of a vinyl ester and a polyethylene glycol or of a mixture of such graft copolymer with a partially solvolyzed polyvinyl ester as well as of water and optionally a polyhydric alkanol. The composition is obtained by mixing the granular polymers used in each case with the other components. It is water-soluble, flowable and thermoplastically workable and is suitable for the preparation of any shaped articles, especially sheets.

  • Patent number: 4287107
    Abstract: The tendency to blocking of polymer sheets can be reduced by means of anti-blocking agents. Suitable anti-blocking agents in transparent polyvinyl butyral sheets are especially montanic acid esters, which do not adversely affect the adhesion of the sheet to glass. The polyvinyl butyral sheets are used as interlayers of laminated glass (safety glass).

  • Patent number: 4009135
    Abstract: The properties of mortar and concrete are improved by the addition to the fresh mortar or concrete of an aqueous dispersion of a plastic obtained by the emulsion polymerization of olefinically unsaturated monomers, and of a polycondensate of formaldehyde and an amino-s-triazine modified with sulfite or sulfonic acid. A well-balanced relation between the compressive strength, the tensile strength in bending, and the adhesion to aged and hardened mortar or concrete is thus obtained.
