摘要：Asphaltic materials (e.g., asphalt, bitumen, or pitch) are increased in flame-resistance and improved in other useful properties by use of a latent catalyst mixturewhich reacts upon heating to catalyze oxidation of the asphaltic material. The catalystcomprises halogenated organic compound which decomposes and releases halogenupon heating and an iron- containing compound adapted to react with the releasedhalogen to form iron halide.
