Disclosed are multi-purpose polymers that are the polymerization product of a monomer mixture comprising at least one amino-substituted vinyl monomer; at least one nonionic vinyl monomer; at least one associative vinyl monomer; at least one semihydrophobic vinyl surfactant monomer; and, optionally, comprising one or more hydroxy-substituted nonionic vinyl monomer, crosslinking monomer, chain transfer agent or polymeric stabilizer. These vinyl addition polymers have a combination of substituents, including amino substituents that provide cationic properties at low pH, hydrophobic substituents, hydrophobically modified polyoxyalkylene substituents, and hydrophilic polyoxyalkylene substituents. The polymers provide surprisingly beneficial rheological properties in acidic aqueous compositions, and are compatible with cationic materials. The multi-purpose polymers are useful in a variety of products for personal care, health care, household care, institutional and industrial care, and industrial applications.
本发明涉及多用途聚合物,其为单体混合物的聚合物化产物,所述单体混合物包括至少一种氨基取代乙烯单体;至少一种非离子乙烯单体;至少一种缔合乙烯单体;至少一种半亲水性乙烯表面活性剂单体;以及可选地,包括一种或多种羟基取代的非离子乙烯单体、交联单体、链转移剂或聚合稳定剂。这些乙烯加成聚合物具有一系列取代基,包括在低pH值下提供阳离子性质的氨基取代基,疏水取代基,疏水修饰的聚氧烷基取代基和亲水性聚氧烷基取代基。这些聚合物在酸性水溶性组合物中提供出人意料的有益流变特性,并且与阳离子材料兼容。这些多用途聚合物在个人护理、健康护理、家庭护理、机构和工业护理以及工业应用的各种产品中非常有用。
