Abstract: This invention relates to polyarylene sulphides (PPS) produced in known manner from optionally substituted halogen benzenes and aromatic polyhalogen compounds, optionally in combination with other polymers, fillers and/or reinforcing fibres, which contain certain N-containing organic bases for reducing the elimination levels of acidic, corrosion-producing volatile constituents and for improving the flow properties thereof.

Abstract: The invention relates to a process for the preparation of aliphatic-aromatic polyamide-imides in the absence of phenols.

Abstract: This invention relates to the use of polyamide imides as thermoplasts.

Abstract: This invention relates to new polyamide imides and to the use thereof as thermoplasts.

Abstract: This invention relates to certain new aliphatic-aromatic polyamidoimides suitable for use as non-clouding electroinsulating lacquers and duroplasts.

Abstract: This invention relates to a new process for the production of polyamide imides.

Abstract: Plasticized polyvinyl alcohol containing one or more 1,4-monoanhydrohexitols and/or one or more 1,4-3,6-dianhydrohexitols and its use for the production of composite films by coextrusion, coating, doubling and lamination.

Abstract: Certain substituted diphenyl ethers improve the flowability of aromatic polyesters and polyester carbonates in the melt.

Abstract: Thermoplastic, branched aromatic polyphosphonates with average molecular weights (number average M.sub.n) of from 11,000 to more than 200,000, obtainable by transesterifying (a) from 97 to 100 moles of at least one diaryl phosphonate, and (b) from 0 to 3 moles of at least one triaryl phosphate--the sum of the moles of (a) and (b) being 100--with (c) from 90 to 99 moles of at least one aromatic dihydroxy compound, and (d) from 0 to 3 moles of at least one aromatic trihydroxy or tetradhydroxy compound--with the proviso that at least one of the components (b) and (d) is present in a quantity of at least 0.001 mole and that, where (b) and (d) are used, the maximum limit on the moles is 3.0.

Abstract: Small quantities of hydrogenated polybenzyls act as a perfect mould release agent for aromatic polyesters based on diphenols and iso- and/or terephthalic acids and do not appreciably impair the elastic strength characteristics, the dimensional stability under heat and the transparency.

Abstract: Aromatic polyesters and polyestercarbonates based on diphenols and iso- and/or terephthalic acids become flame-proof if admixed with small quantities of ammonium or alkali metal salts of inorganic or organic acids and optionally halophthalimides and optionally polytetrafluoroethylene. The mechanical and chemical properties of the polyester (carbonates) remain unchanged.

Abstract: A flame-retardant composition comprising a polyphenylene ether and a polystyrene resin in a weight ratio of between 4:1 to 1:4 in admixture with an aromatic thermoplastic polyphonate having a number average molecular weight of 4,000 to 80,000, said thermoplastic polyphosphonate being present in an amount of 1 to 20 parts by weight per 100 parts by weight of the total mixture.

Abstract: Aromatic polyesters based on diphenols, terephthalic and isophthalic acid and particular chain terminators exhibit an improved color number, an improved flowability and increased dimensional heat stability with otherwise comparable mechanical characteristics.

Abstract: Thermoplastic, branched aromatic polyphosphonates with average molecular weights (number average M.sub.n) of from 11,000 to more than 200,000, obtainable by transesterifying (a) from 97 to 100 moles of at least one diaryl phosphonate, and (b) from 0 to 3 moles of at least one triaryl phosphate--the sum of the moled of (a) and (b) being 100--with (c) from 90 to 99 moles of at least one aromatic dihydroxy compound, and (d) from 0 to 3 moles of at least one aromatic trihydroxy or tetrahydroxy compound--with the proviso that at least one of the components (b) and (d) is present in a quantity of at least 0.001 mole and that, where (b) and (d) are used, the maximum limit on the moles is 3.0.

Abstract: Polyester phosphonates based on aromatic dicarboxylic acids and aromatic dihydroxy compounds exhibit a low flammability and surprisingly improved mechanical characteristics, particularly an excellent dimensional heat stability.

Abstract: High-molecular polyesters which are distinguished by good processability, a high glass transition temperature, mechanical strength and clear transparency are reproducibly obtained by transesterifying and polycondensing bisphenols with diaryl terephthalates and/or diaryl isophthalates in the presence of an aromatic polycarbonate having a molecular weight of 600 to 15,000.
