Water-soluble or water-swellable polymers ionic in ncharacter and having surface-active properties are nprovided which are based on a lipophilic monomer, which nmay be an ionic, nonionic and anionic water-soluble nmonomer, the latter monomer being further characterized nby its homopolymer being soluble in water at a pH in the nrange of 2 to 14. Other monomers may be present. It is npreferred that these be water-soluble. The polymers are nprepared generally in the usual manner employed for α,β-nethylenically unsaturated compounds. The products have na myriad of uses, such as thickeners, water-treating naids, sewage treatment, superabsorbers, etc. |
