    摘要： Sulfur-containing polymers, such as polyphenylene sulfide, are stabilized from releasing sulfur-containing exhaust gases by adding an additive polymer having at least one reactive radical selected from the group consisting of amino radicals, amido radicals, imido radicals, and keto radicals therein, and which is of approximate the same thermal stability as the sulfur-containing polymer, to such sulfur-containing polymer. In other embodiments of the invention, sulfur-stabilization is also achieved by incorporating suitable fundamental building blocks of the additive polymer into the sulfur-containing polymer chain in the form of reactive monomers. Further, in other embodiments, additive polymers or oligomers (so-called telecheles) having reactive radicals at their ends can be introduced into the sulfur-containing polymer chain as copolymers. In addition, low molecular weight compounds having high boiling points and having structures similar to the fundamental building blocks of the sulfur-containing polymers are also effective for stabilizing such polymers.

    摘要： Glass or vitrified carbon is produced by thermal degradation of polyphenylene sulfide or a substituted compound thereof by additions of an oxide of a sulfide-forming metal, such as Fe.sub.2 O.sub.3, which is added in a weight amount of at least about 1% and preferably about 10%, in order to accelerate the degradation process, and resultant admixture is heated to a temperature above about 150.degree. C. and thereafter the temperature is increased during the course of the reaction. The inventive process is useful for production of chemically resistant glass carbon fibers, glass carbon electrodes, glass carbon containers, etc.
