ABSTRACT:
The subject invention relates to a process for treating an emulsion of a crosslinked elastomeric polymer containing residual hydrazine to obtain a latex of soluble elastomeric polymer having a reduced concentration of residual hydrazine therein, said process comprising the addition of ozone to said emulsion in an amount and under conditions which are sufficient for the ozone to react with the crosslinked elastomeric polymer and the residual hydrazine to produce a latex of soluble elastomeric polymer having a reduced level of residual hydrazine therein. The process of the present invention also improves the color of latex by removing color-bodies, such as benzoquinone, which may be present in the original latex.
