    摘要: The invention relates to a new three-part process, which can also be employed on a large industrial scale, for the preparation of polyurea lubricating greases, which is characterised(a) in that polyureas which carry oleophilic groups are prepared by reaction of diisocyanates with amines either in the absence of a solvent on a reaction screw at 80.degree.-120.degree. C., preferably at 85.degree.-95.degree. C., (variant A) or in a toluene medium at 20.degree.-80.degree. C., preferably at 30.degree.-60.degree. C., (variant B),(b) in that, after complete reaction, the polyureas prepared according to (a) are ground in the solid, dry state to give powders (at least 70% by weight of the powder having particle sizes of about 100-400.mu.) and(c) in that the ground crude product, after being made into a "paste" (wetted) at elevated temperature in the base oil employed (10-30 minutes at 140.degree.-180.degree. C.) and cooled again to room temperature, is processed to a grease by complete homogenisation--if appropriate in several passes--in a high-pressure homogeniser under a pressure of 400-1,500 bar (spontaneous heating occurring up to about 100.degree. C.),greases having readily reproducible and essentially the same properties as in the case of the previously customary in situ manufacture being produced.

    摘要: Biological material such as microorganisms is immobilized by polymerizing in the presence of the biological material a readily soluble polyetherpolyol having some hydroxyl groups esterified with acrylic and/or methacrylic acid and remaining hydroxyl groups reacted with an isocyanate group-containing derivative of an unsaturated carboxylic acid or a polyfunctional isocyanate. Preferably, the isocyanate derivative of an unsaturated carboxylic acid is isocyanatoethyl acrylate, isocyanatoethyl methacrylate of 4-isocyanato-3-methyl-2-butyl-acrylate and the polyfunctional isocyanate is a diisocyanate or polyisocyanate. Beads can be produced by forming droplets in a water-immiscible medium and polymerizing. Polymerization can be carried out under inert gas in the presence of radical initiators or by irradiation with actinic light.
