Abstract

A polymerized anionic surfactant is prepared from the regeneratable oil of natural animal or plant, amidation reaction, creating linking group by epoxy chloropropane, adding hydrophilic group y sulfonating reaction, and linking by particular linking group.

Description

technical field [0001] The invention belongs to an active agent and a preparation method, in particular to a polymeric anionic surfactant and a preparation method. Background technique [0002] The structure of polymeric surfactants was synthesized abroad as early as the 1970s, but it was after the 1990s that it was truly recognized that surfactants with such structures have high surface activity. The international research on polymeric surfactants has been really carried out in the last ten years. Some foreign products have industrial applications. Domestic research units in this area include the Department of Chemistry of Fuzhou University and the Institute of Chemistry of the Chinese Academy of Sciences. Cationic polymeric surfactants are produced by domestic manufacturers such as Guangzhou Zhenke Technology Development Co., Ltd. Henan Daochun Chemical Technology Co., Ltd. The application amount of cationic surfactant accounts for a few percentage points in the whole su...
