Abstract: A composition for coating a cellulosic packaging material that includes water, starch at a concentration of about 10% to about 17% by weight, gelatin at a concentration of about 10% to about 12% by weight, glycerol at a concentration of about 5% to about 11% by weight, one or more protein ingredients at a concentration of about 5% to about 10% by weight, and one or more porophors at a concentration of about 3% to about 5.5% by weight. The present invention also relates to a method of preparing the composition for coating cellulosic packaging material.

Abstract: A method for the producing of an agent for the removal of dissolved phosphorus compounds from water, relying on the formation of the biopolymer metal compound system which is characterized by that, the natural plant fibers are subjected to the activation, subsequently the activated natural plant fibers are coated with biopolymer or derivatives thereof with the ionic character. The natural plant fibers are coated with at least one water-soluble polyvalent metal compound before or after coating the natural plant fibers with biopolymer or derivatives thereof with the ionic character. Such modified natural plant fibers form a composite fibrous material in the form of biopolymer hydrogel support crosslinked in the presence of water-soluble polyvalent metal compound support on the warp from natural fiber.

Abstract: Agent for removing dissolved phosphorus compounds from water according to the invention, containing a biopolymer and metal compound, is characterized by being in the form of spherical capsules which contain the biopolymer or derivatives thereof with the ionic character crosslinked in the presence of at least one water-soluble polyvalent metal compounds.

Abstract: The use is described of monohydroxy-terminated polybutadienes as reactive or internal plasticizers for polyurethanes. The polyurethanes are made in conventional manner by reacting at least one polyisocyanate with at least one polyol under polyurethane-forming conditions, which may include the presence of a catalyst. In accordance with the invention this reaction is carried out in the presence of a monohydroxy-terminated polybutadiene which may have a molecular weight of 500 to 100,000, preferably 900 to 20,000. As a monohydroxy-terminated polybutadiene is a constituent of the resulting polyurethane, the use of a polybutadiene diol as the polyol is excluded. Short chain polyols and conventional additives may be present and the resulting polyurethane may be in the form of a solid or a foam.
