Abstract
An amino methylenesulfonic acid comprising the reaction product of an amine compound (eg) a substituted succinimide containing free primary or secondary nitrogen atoms or a compound of the formula R.sub.1 NH--CH.sub.2 CH.sub.2 CH.sub.2 NH.sub.2 or RNH.sub.2 wherein R and R.sub.1 have 1 to 25 carbon atoms; a compound of the formula ##STR1## wherein R.sub.2 is a hydrogen or a methyl group and R.sub.3 is a hydrogen or an alkyl group having from about 1 to 7 carbon atoms and sulfur dioxide; which can be alternatively reacted with a polyfunctional crosslinking agent; and mixtures of the amino-methylene sulfonic acid with a nitrogen compound adduct of a maleic anhydride olefin copolymer.
Claims5
