Abstract: NEW FILM- AND FIBER-FORMING HIGH MOLECULAR WEIGHT AROMATIC COPOLYAMIDE-PHOSPHONAMIDES ARE OBTAINED BY ADDING A PHOSPHONIC ACID DIHALIDE AT ELEVATED TEMPERATURE TO A MELT OF AT LEAST ONE AROMATIC DIAMINE IN EXCESS, BY DISSOLVING THE REACTION PRODUCT, AFTER COMPELTE REACTION, IN A SOLVENT OF THE AMIDE KIND, BY ADDING AT LEAST ONE AROMATIC DICARBOXYLIC ACID HALIDE TO THIS SOLUTION AT A TEMPERATURE OF FROM ABOUT -20* TO +30*C., AND THUS POLYCONDNESING IT TO FORM A HIGH MOLECULAR WEIGHT AROMATIC COPOLYAMIDE-PHOSPHONAMIDE. SHAPED ARTICLES MADE FROM THESE COPOLYAMIDE-PHOSPHONAMIDES ARE DISTINGUISHED BY THEIR GOOD AFFINITY TO DYESTUFFS AND POOR FLAMMABILITY.

Abstract: A process is described for the production of a carrier web of a spun bond consisting of synthetic polyester filaments having a melting point of more than 230 DEG C and a filament titer of approximately 3 to 15 dtex. To this spun bond, a chemical binder is applied in the form of an aqueous dispersion which is dried at approximately 120 DEG to 220 DEG C. The dispersion consists of (A) 10 TO 60% BY WEIGHT OF A COPOLYMER OF 60 TO 90% BY WEIGHT OF STYRENE, 5 TO 20% BY WEIGHT OF BUTADIENE, 2 TO 10% BY WEIGHT OF ACRYLIC ACID AND 2 TO 10% BY WEIGHT OF ACRYLAMIDE, (B) 5 TO 30% BY WEIGHT, CALCULATED ON THE AMOUNT OF COPOLYMER, OF A MELAMINE FORMALDEHYDE PRECONDENSATE, (C) A CATALYTIC AMOUNT OF ACID CATALYSTS, AS WELL AS, OPTIONALLY, (D) FURTHER INERT ADDITIVES.

Abstract: Shaped articles made from expanded minerals obtained by treating a mixture of a hydrophobized expanded mineral and a calcium aluminate with an aqueous solution of aluminum phosphate, and subsequently consolidating it under the action of pressure and heat; the expanded mineral having been hydrophobized with a hydrophobizing agent consisting substantially of (a) a fatty amine of the formula in which R1 is C8-C22-alkyl, preferably C14-C22-alkyl, C14-C22-alkenyl or C8-C22-alkylphenyl, R2 and R3 each are hydrogen, C1-C4-alkyl or C2-C4-alkenyl, phenyl or benzyl, and n is a number of from 0 to 4; (b) a fatty acid of the formula R5CO(OCH2CH2)mOH or a fatty alcohol of the formula R6(OCH2CH2)mOH in which R5 is C8-C22-alkyl, preferably C14-C22-alkyl or -alkenyl, R6 is C9-C23-alkyl, preferably C15-C23-alkyl or -alkenyl, and m is a number of from 0 to 2; and (c) a low molecular weight acid.
