    摘要： A release agent applied to the surface of a mold in the form of a film to permit ready removal of plastic, particularly polyurethane, from the mold. The release agent contains a film-forming substance having an affinity to the plastic and becomes attached to the plastic and is removed with the plastic when taken out of the mold thereby preventing buildup of film-forming substance in the mold. A cross-linking agent and/or a cross-linking catalyst and/or emulsifier and/or tenside may advantageously be incorporated in the release agent.

    摘要： The instant invention relates to an improved process for the production of cellular or non-cellular polyurethane urea elastomers, in which diamines which contain ester groups are used as chain lengthening agents. A characteristic feature of the process according to the invention is the use of salts of aromatic diaminocarboxylic or sulphonic acids as a portion of the chain lengthening component. Elastomers produced by this process are distinguished by their improved mechanical properties, in particular their increased tensile strength and tear propagation resistance as well as their reduced permanent elongation.

    摘要： Waterinsoluble polyazo dyestuffs of the formulaX(O-OC-D-N=N-K).sub.mIn which K denotes identical or different radicals of a coupling component, X denotes an aliphatic radical which is free of hydroxyl groups and is optionally interrupted by heteroatoms, or an aromatic-carbocyclic, aromatic-heterocyclic or araliphatic radical, D represents an aromatic-carbocyclic or aromatic-heterocyclic radical and m represents the numbers 2 or 3. These dyestuffs are useful as dispersion dyestuffs for coloring synthetic fibers and most especially as pigment dyestuffs for coloring paint, inks, paper, and macromolecular substances and for admixing with other substances such as inorganic white pigments including titanium dioxide.
