Abstract

1355709 Deodorizing polymer dispersions BASF AG 26 Aug 1971 [27 Aug 1970] 40064/71 Heading C3P The deodorization of an aqueous dispersion of a polymer of an alkyl ester of an alpha, beta ethylenically unsaturated carboxylic acid optionally containing units derived from one or more other ethylenic monomers, which dispersion has an odour due to the presence of unpolymerized ester, is effected by treating the dispersion with a compound containing one or more basic non-tertiary nitrogen atoms (except ammonia and ethylene imine), which reacts with the ester to form a monodiferous product. The term "alkyl" includes substituted alkyl. Preferred compounds are those of the formula (I) wherein R is H, alkyl, alkenyl, alkoxyalkyl, hydroxyalkyl, or aralkyl and X is an aliphatic or cycloaliphatic saturated or unsaturated hydrocarbon radical containing one or more aryl groups and/or hetero atoms selected from amino and amido nitrogen atoms, and amide, ether and hydroxy oxygen atoms or a compound of general formula in which Y is -CH 2 -, -O-, -S-, or =NR<SP>11</SP>, where R<SP>11</SP> is H, hydroxy alkyl, aminoalkyl, mono- or dialkyl amino alkyl, alkyl, alkenyl, alkoxyalkyl, aralkyl or acyl, m is zero or 1 or (only when Y is -S- or = NR<SP>11</SP>) 2, and n and o are zero or integers from 1-4 provided that m = 1 or 2 when n and o are both 1, and provided that m+o equals at least 2, and provided that any methylene group may be replaced by a substituted methylene group or any pair of adjacent methylene groups may be replaced by a vinylene group. A long list of examples is given. The treatment is preferably carried out at 40-80‹ C. and pH 5 to 12. In the examples the following treatments are effected on aqueous dispersion of the polymers specified; (1) styrene/n-butyl acrylate with piperazine, dimethylamine and morpholine; (2) styrene/2-ethyl hexyl acrylate with oleyl amine; (3) styrene/n-butyl acrylate/methacrylamide/methacrylic acid with 3-(2-ethyl)-hexoxypropylamine; and (4) styrene/n-butyl acrylate/ methacrylamide with ethylamine.
