Abstract: With the present invention, sustainable systems for corrosion, inhibition in the processing of metals (in particular iron, aluminum and magnesium) are made available. These systems being in full accordance with the principles of green chemistry comprise an amino acid as neutralizing component for an acidic corrosion inhibitor, whereby the amino acid is used in deprotonated form. The resulting metalworking fluids may be water- or oil-based or semi synthetic formulations. The neutralization of acidic corrosion inhibitors with the claimed system comprising an amino acid consistently achieves convincing results and, together with acidic corrosion inhibitors from corresponding sources, completely renewable systems for corrosion inhibition are provided.

Abstract: The invention relates to a method for producing a covering layer for elastic laminate comprising a) impregnating a carrier fabric, b) applying a surface coating comprising a crosslinker and a prepolymer that can be crosslinked via reactive end groups, c) crosslinking the crosslinkable prepolymer, and d) drying the elastic laminate covering layer. The papers obtainable in this manner are suitable for producing a laminate that, with the elastic outer face thereof, has a pleasant and appealing feel underfoot and good haptics.

Abstract: The present invention is directed to novel surface active copolymers and the use thereof in the production of polyurethane powders. More particularly, the copolymers comprise have a substantially linear structure and are obtained by copolymerization ofA) a partial reaction product of1) (meth)acrylic acid or a derivative thereof and2) a macromolecular compound substituted by at least two functional groups selected from OH and NH.sub.2, the functional groups not reacted with Al) being irreversibly blocked, withB) a urethane of 1) a long-chain alkyl isocyanate and 2) a hydroxyalkyl (meth)acrylate.

Abstract: The present invention is directed to an improved process for the direct preparation of polyurethane powders in a finely divided form by the reaction of polyisocyanates and isocyanate reactive compounds in a carrier phase, using interface active compounds, the improvement wherein the interface active compound used consists of at least one polymer of a urethane of (i) a long chain alkyl isocyanate and (ii) a hydroxyalkyl-acrylic or -metacrylic acid ester.

Abstract: The present invention is directed to polyethers obtained by the reaction of a substituted 1,2-epoxy-alkane bearing at least one alkyl substituent containing at least 8 carbon atoms with at least one polyol corresponding to the formulaR(OH).sub.x (1)whereinR is an organic radical andx is an integer having a value of 2 or more,2 or more moles of epoxyalkane being added onto the polyol (1).The present invention is also directed to a process for the preparation of high molecular weight polymers wherein the process is conducted in the presence of the previously described polyethers as a mold release agent.
