ABSTRACT:
Preparation of satisfactory asphaltic roofing fluxes from otherwise unsatisfactory fluxes is disclosed to involve addition of asphaltenes, and saturates in quantities which satisfy certain specified conditions. Air oxidation of a flux is shown to be surprisingly accelerated by the addition of highly branched saturates, especially in the presence of a carbonate oxidation catalyst.
