Abstract
Compounds having the formula ##EQU1## wherein R is alkyl group having 6 to 22 carbon atoms, M is H, Li, Na, K or NH.sub.4 and n is an integer of 2 to 4, inclusive. The compound is useful as polymerizable emulsifying agent, and enables to improve properties of produced polymer and to provide a modacrylic fiber superior in heat stability and fastness to light. The aqueous emulsion polymerization of .alpha.,.beta.-ethylenically unsaturated monomer by the use of the polymerizable anionic emulsifying agent is capable of preventing a discharge of an environmental pollutant.
