  • Patent number: 6656984
    Abstract: The invention relates to a hydrophobic polymer dispersion and a solvent-free process for the preparation thereof. According to the invention, the dispersion contains starch ester together with dispersion admixtures known as such. According to the process, the polymer is first mixed with a plasticizer in order to obtain a plasticized polymer blend. The plasticized polymer blend is then mixed with dispersion admixtures and water at an elevated temperature so as to form a dispersion. The plasticizing of the polymer and the dispersion of the mixture in water can be performed in an extruder. The obtained dispersion is homogenized in order to improve its stability. The dispersion obtained by the invention can be used to coat paper or board, as a primer or a component in paint or labeling adhesives, and it is also suitable for the production of cast films and as a binder in materials based on cellulose fibers, as well as for coating medicinal preparations.

Thermotropic molding compounds of this kind are used, amongst other things, for glass and coverings for shading and light/heat regulation in houses, cars, etc. The molding compound according to the invention consists of two compounds which are not thermodynamically miscible with one another. The first component consists of a plastics material, while the second component is not liquid-crystalline and has a refractive index which is the same as the first component in the transparent range and the temperature dependency of which is different from the temperature dependency of the refractive index of the first component. On raising the temperature, the transmission of the molding compound is thus altered.

  • Publication number: 20010021733
    Abstract: The invention relates to a new process for preparing polymer dispersions. According to the invention, a mixture is first formed of a polymer component, a plasticizer, dispersion auxiliaries and water, the mixture is then heated to approximately 20 to 100° C. in order to form a paste-like composition, and the paste-like composition is dispersed in water. The dispersion obtained according to the invention can be used for coating paper or board, as a primer, as a component in adhesives, paint or lacquer, and it is also suited for the manufacture of cast films and for use as a binder in materials based on cellulosic fibers.
