Abstract

The invention discloses a hyperbranched surfactant and a preparation method thereof. According to the invention, a hyperbranched polyesteramine polymer with an amino terminal is synthesized, and the amino terminal is subjected to active chain segment modification, so that a hyperbranched surfactant with the hyperbranched polymer as an inner core and an active chain segment as a shell can be obtained. The hyperbranched surfactant provided by the invention has a spatial three-dimensional structure and a unique hole structure, so that the hyperbranched surfactant has good surface / interface activity, thereby having great advantages in the aspects of wetting, washing, emulsifying, compatibilizing and the like. The hyperbranched surfactant is simple in preparation method, environment-friendly in process and excellent in performance.

Description

technical field [0001] The application relates to a surfactant and a preparation method thereof, belonging to the field of surfactants. Background technique [0002] Hyperbranched polymers are homologues of dendritic polymers, which are a type of highly branched three-dimensional macromolecules. , Several layers of branch units and peripheral groups are connected by chemical bonds. Although the structure of hyperbranched polymers is not as perfect as that of dendrimers, its physical and chemical properties are close to those of dendrimers. Hyperbranched polymers have many branch points, the molecular chains are not easy to entangle, the viscosity does not change with the increase of molecular weight, and there are abundant terminal functional groups, which are easy to modify and modify, which is conducive to the synthesis of various functional materials. In addition, the synthesis of dendritic polymers is relatively complicated, and generally requires step-by-step protecti...
