Water-soluble or water-swellable polymers ionic in character and having surface-active properties are provided which are based on a lipophilic monomer, which may be an ionic, nonionic and anionic water-soluble monomer, the latter monomer being further characterized by its homopolymer being soluble in water at a pH in the range of 2 to 14. Other monomers may be present. It is preferred that these be water-soluble. The polymers are prepared generally in the usual manner employed for α,β-ethylenically unsaturated compounds. The products have a myriad of uses, such as thickeners, water-treating aids, sewage treatment, superabsorbers, etc.
本发明提供了具有表面活性的离子型水溶性或水溶性聚合物,这些聚合物以亲脂性单体为基础,亲脂性单体可以是离子型、非离子型或阴离子型水溶性单体,阴离子型单体的进一步特征是其均聚物在 pH 值为 2 至 14 的范围内可溶于水。也可以加入其他单体。这些单体最好是水溶性的。聚合物的制备方法通常与 α、β-乙烯基不饱和化合物的制备方法相同。产品用途广泛,如增稠剂、水处理助剂、污水处理、超级吸收剂等。
