Abstract
Processes are disclosed for the selective hydrolysis of saturated esters, e.g., ethyl propionate, over unsaturated esters, e.g., ethyl acrylate, using enzymes, e.g., lipases. The processes are useful, for example, for removing undesired esters from monomer feeds used in latex polymerization and from the latexes after polymerization. The processes can be used, for example, to treat latexes used in hair fixative compositions to remove unpleasant odors.
