The invention discloses a polymer emulsion, which can be composed of α, β-vinyl unsaturated carboxylic acid monomer (I) and/or an acid monomer with sulfonic acid, phosphoric acid or hypophosphorous acid, α, β-vinyl unsaturated carboxylic acid monomer (I) Saturated monomer (II), hydrophilic unsaturated crosslinking monomer or difunctional and polyfunctional ethylenically unsaturated crosslinking monomer (III~VI), nonionic vinyl or acryloyl surfactant (VII), The anionic emulsifier reacts with an initiator and a chain transfer agent to prepare the polymer emulsion, which can be used in a surfactant composition to form a binary system. Due to the unique cross-linking nodes in the emulsion polymer, it can be used as an effective and efficient thickener in many applications, such as cosmetics, pharmaceuticals, latex paints, and cleaning compositions, even in harsh environments with low pH and high salt content with suspending agent. |
