摘要： A process for the manufacture of flame-resistant threads, fibers, and films and the like products that contain a synthetic polymer and cellulose, which comprises processing a mixture of viscose and an aqueous alkaline solution of a polyacyloxalamidraxone such as polyterephthaloyloxalamidrazone to form a thread or like product, immersing the product in a treatment bath that can be neutral acidic or alkaline in which bath it is allowed to react with a solution of one or more metal compounds, e.g., zinc chloride, tin chloride, and/or barium chloride, and thereafter washing and drying the resulting product.

摘要： An aqueous alkali metal hydroxide solution in which there is dissolved a polyacyloxamidrazone, the resulting alkaline polymer solution being useful for the production of heat-resistant shaped products such as filaments, films, coatings and the like. A process for producing these products includes the steps of forming the polymer solution into a filament or film in contact with an acid precipitation bath, washing the precipitate and subsequently heating to a temperature of approximately 230*350*C. It is known that polytriazoles can be obtained by the reaction of dinitriles with dihydrazides or by heating cyanocarboxylic hydrazides. The resulting products are resistant to high temperatures, particularly if they contain aromatic groups in the polymer chain.
