Abstract: Polythiadiazoles of formula (I) where R1 is a (cyclo)aliphatic, aromatic or heterocyclic residue, and n = 5-100, are claimed (I) are promoters for polymer breakdown, bonding agents for polymers, and intermediates for dyes. (I) is prepd. by the reaction of a dialdehyde of formula OHC-R1-CHO with hydrazine and S, in molar ratio about 1:1:1, at 10-180 degrees C. If a small excess of dialdehyde is used, the chain endings are satd. by OHC- or -R-CHO gps. Reaction is pref. at 30-150 degrees C. in a solvent and at up to 50 bars pressure. The prods. are colourless to pale yellow polymers with decomposition temp.>150 degrees C. and mol. wt. 1,000-20,000.

Abstract: New aromatic polyamide-imides (I) with 1,3,4-thiadiazole gps. consist of units of the formula (in which Y has the formula n = 100-10,000. Ar1 is a m- or p-aryl gp. Ar2 is as Ar1 or -Ar3-Y'-Ar4; Ar3 and Ar4 are as Ar1. Y' is Y, S, O, SO2, CO or a direct bond). Fibrides, fibres, films, foams, insulating lacquers, coating compsns. and laminates can be made from (I) solns., according to the mol. wt., and the pptd. (I) can be moulded by hot pressing. (I) have better thermal stability than aromatic olyamides with Y gps. and an ether and/or sulphonic acid gp. and can be produced from solns. usin readily available starting materials. (I) have terminal carboxyl, urea, amido and/or amino gps. (I) are prepd. by reacting trimellitic acid or anhydride (II) with H2N-Ar1-Y-Ar1-NH2 and then with OCN-Ar2-Y'-Ar2-NCO. E.g. a 22% soln. of (I) with a soln. viscosity of 34600 cP at 20 degrees C and intrinsic viscosity of 0.8 dl/g was prepd. from 0.5 mole (II), 0.25 mole H2N-O-Y-O-NH2, 0.25 mole OCN-0-O-0-NCO and 0.003 mole OCN-0-CH2-0-NCO (in which 0 is p-phenylene).

Abstract: Thermoplastic molding compositions based on styrene polymers contain, as a flameproofing agent, an organic bromine compound of the general formula where X is a hydrocarbon radical and n is 0 or 1. The compositions may be used for the manufacture of self-extinguishing moldings, e.g. foams.
