<p>Novel water soluble vinyl-type polymers are described which are either homopolymers or copolymers of monomers of the general formula < IMG > in which: m is hydrogen, lithium, sodium, potassium, magnesium, or calcium; R is allyl or methallyl Rl is hydrogen, allyl, or methallyl R2 is hydrogen or sulfonato, and R3 is hydrogen or sulfonato provided that R2 is not the same as R3. There monomers possess the advantage of providing a sulfonate-group containing polymer directly, without having to apply a sulfonation procedure to the polymer. A typical comonomer is acrylic acid.</p> |
