ABSTRACT:
Continuous oxidation of rubbery polymeric hyrocarbons by mixing an oxygen-containing gas and a hot solution of the polymer in an oleaginous solvent at the inlet to a spraying device and spraying the mixture into a hot chamber provides substantially instantaneous oxidation of the polymer and disengagement of gas and liquid and at least the same extent of oxidation as the time consuming oxidation accomplished by sparging such gas into a volume of stirred hot solution.
