    摘要: Permanently flame-resistant synthetic linear polyesters are obtained by irporating by condensation into the polyester composed of the usual dicarboxylic acid and diol units an alkylphosphine oxide of the formula ##SPC1##Wherein the radicals R to R.sub.4 represent organic radicals of which R.sub.2, R.sub.3 and Z may be substituted by 2 hydroxyl groups altogether, R.sub.2, R.sub.3 and R.sub.4 may also represent hydrogen and a is zero or a whole number of from 1 to 4. The flame-resistant polyesters are processed into shaped structures such as fibers, filaments, sheets, injection and compression molded articles characterized by good flameproofness and dyeing properties.

    摘要: The present invention relates to novel agents for the flame-proofing of polymers, especially transparent polyamides. These agents, phosphinylphosphinic acids, are used in quantities of 3 to 40 weight percent calculated on the weight of the polymer. These flame-proofing agents can easily be prepared and render the polymers flame-proof to a high degree without deteriorating the mechanical and physical properties.

    摘要: Salt mixtures made from aluminum phosphinates, aluminum hydroxide and/or aluminum phosphonates and/or aluminum phosphates are thermally stable and are suitable as flame retardants for polymeric molding compositions, in particular for polyesters and polyamides. The use of these salt mixtures is more effective and more cost-effective than the use of aluminum phosphinates alone.
