ABSTRACT:
A method for reducing residual unsaturated monomer content of an aqueous dispersion of a saturated polymer. The method involves contacting the aqueous dispersion with ozone resulting in ozonolysis of unsaturated monomers. The method is simple, economical and can be used with existing production facilities.
