摘要： A method of decomposing a polycarbonate with water in a supercritical or subcritical state. A high-purity dihydroxy compound which is a constituent component of the polycarbonate can be recovered at a high yield by this decomposition method. This decomposition method is environment-friendly because it does not use an organic solvent, easy to be carried out, has a high decomposition rate and rarely causes a side reaction.

摘要： A shaped silicon carbide-based ceramic article having an improved mechanical strength is produced at a high efficiency by a process comprising the step of: forming an organic silicon polymer, for example, polycarbosilastyrene copolymer, into a predetermined shape, for example, a filament or film; doping the shaped polymer with a doping material consisting of at least one type of halogen, for example, bromine or iodine, in an amount of 0.01% to 150% based on the weight of the shaped polymer, to render the shaped polymer infusible; and pyrolyzing the infusible shaped polymer into a shaped SiC-based ceramic article at a temperature of 800.degree. C. to 1400.degree. C. in an inert gas atmosphere, optionally the halogen-doped shaped polymer being treated with a basic material, for example, ammonia, before the pyrolyzing step, to make the filament uniformly infusible.
