Abstract
Disclosed are ethylenically unsaturated amine salts of sulfonic, phosphoric and carboxylic acids. The salts are surface active agents which are useful in a variety of applications as primary and/or secondary surfactants. The salts are especially useful as surfactants in emulsion polymerization reactions.
Claims10
A polymerizable surface active agent comprising an amine salt comprising:
- a) a conjugate base derived from an acid of the formula R1—CH(SO3H)CO2R2, wherein R1 is a saturated or unsaturated hydrocarbon group having from about 6-24 carbon atoms;
- R2 is methyl, ethyl, or propyl, or a mixture thereof;
- and
- b) a conjugate acid derived from a nitrogenous base, wherein the nitrogenous base is selected from the group consisting of allyl amine, diallyl amine, triallyl amine, methallyl amine, N-methyl N-allyl amine, 2-(dimethylamino)ethyl acrylate, and mixtures thereof.
