NON-FLUOROSURFACTANT, PREPARATION METHOD THEREFOR, AND USE THEREOF
20260035499 · 2026-02-05 ·

Provided in the present invention are a non-fluorosurfactant, a preparation method therefor, and the use thereof. The non-fluorosurfactant is a polymer, the main chain of which contains the following structural units: structural units A, structural units B, structural units C and structural units D, wherein the structural units D are linked to each other by means of (I), R.sub.1, R.sub.2, R.sub.4, R.sub.5, and R.sub.6 are each independently a hydrogen atom or C.sub.1-C.sub.3 alkyl group, R.sub.3 is a hydrogen atom, NH.sub.4.sup.+, or a monovalent metal ion, and n is an integer of 10-150. The non-fluorosurfactant provided by the present invention has a good effect of reducing the surface tension of an aqueous phase system, and therefore can be used for preparing a fluorine-containing polymer in replacement of fluorine-containing surfactants.
