| 摘要 |
Carbonaceous pyropolymers possessing recurring units containing at least carbon and hydrogen atoms may be obtained from compositions of matter comprising carbonaceous pyropolymers possessing recurring units containing at least carbon and hydrogen atoms composited on an inorganic metal oxide support or substrate by treating the composition of matter with a chloride-containing compound at an elevated temperature in the range of from about 400 DEG to about 1000 DEG C. in the vapor phase. The resulting metal chloride such as aluminum chloride is continuously removed from the composite, leaving only the carbonaceous pyropolymer.
