    摘要: Fiber-containing polyurethane foams having improved compression properties, especially at deformations of greater than 50%, are obtained by incorporating in the foam-forming composition from 0.1 to 10% by weight, based on the weight of finished foam, of polyolefin fibers, e.g., polyethylene or polypropylene fibers, that have been treated to provide them with functional groups that are reactive with isocyanates. The reactive fibers may be obtained by fixing to the fiber surface or incorporating in the fiber polyfunctional compounds, e.g., starch, methylcellulose, carboxy methylcellulose, saccharin, polyglycols, polyvinyl alcohol, hydroxyl-group-containing block copolymers, completely saponified copolymers of ethylene and vinylacetate and oxidation products of a polyolefin.

    摘要: Polyamides of the general formula [N(A)-X-N(B)-CO-Y-CO-].sub.n are described, in which Y denotes a divalent group, X a divalent radical whose chain contains at least two carbon atoms, A and B independently of one another denote H or a C.sub.1 to C.sub.26 alkyl group and n denotes an integer greater than 4. The said polyamides contain at least one alkyl group of C.sub.6 to C.sub.26 per repeating unit. The groups X and/or Y contain at leat one CH.sub.2 group in the chain. The polyamides are prepared by reaction of a diamine of the formula NHA-X-NHB with an about equimolar amount of a reactive derivative of a dicarboxylic acid of the formula COOH-Y-COOH. The polyamides obtained can be used in order to prepare highly ordered monomolecular LB films on a support. For this purpose, the polyamide is dissolved in a volatile organic solvent which is immiscible with water and the solution is spread on the water/air interface. After evaporation of the solvent the layer is compressed and transferred to a solid support by the LB technique. The film is very stable and can be used to prepare optical waveguide systems, filters for optical purposes or protective layers.
