ABSTRACT OF THE DISCLOSURE Novel water-soluble vinyl addition monomers are des- cribed generally by the formula: Image wherein: M is hydrogen, lithium, sodium, potassium, magnesium, or calcium; R is allyl or methallyl; R1 is hydrogen, allyl or methallyl; R2 is hydrogen or sulfanato; R3 is hydrogen or sul- fanato; and providing that R2 is not the same as R3. These monomers possess the advantage of providing a sulfonated poly- mer directly, without having to resort to polymer sulfonation techniques. These monomers also provide both homopolymers and copolymers, with other vinyl-type monomers such as acrylic acid and dimethyl diallyl ammonium chloride.
