Abstract:
A process for reducing free aldehydes in a polymer dispersion, polymer suspension, polymer emulsion, polymer solution, or aqueous fat emulsion for which aldehyde reduction is desired, the process comprising incorporating into said polymer dispersion, polymer suspension, polymer emulsion, polymer solution, or aqueous fat emulsion a thioalkylamine of the formula IV, optionally in admixture with one or more thioalkylamines of the formula III: where R1 is an alkyl radical of up to 5 carbon atoms, an aryl radical, or hydrogen, R2 is â€”(COO)aâ€”E or â€”(CONH)aâ€”E, where a is 0 or 1 and E is an organic radical of up to 10 carbon atoms or hydrogen, R3 is a monovalent organic radical of up to 10 carbon atoms or hydrogen, R4 and R5 represent organic radicals of up to 10 carbon atoms or hydrogen and may be bonded to each other, subject to the proviso that R4 and R5 together must contain at least one carbon atom, and n is 0 or 1, wherein said thioaklylamines of formulae III and IV may be present in the form of their respective salts and/or esters.
