Abstract

The invention discloses a polymer latex which can be obtained by the reaction among alpha, beta-vinyl unsaturated carboxylic acid monomer (I) and or acid monomer with sulfonic acid, phosphoric acid or hypophosphorous acid, alpha, beta-vinyl unsaturated monomer (II), hydrophilic unsaturated crosslinking monomer or bifunctional and multifunctional vinyl unsaturated crosslinking monomer (III-VI), nonionic vinyl or acryl surface active agent (VII), anionic emulsifier, initiator, and chain transfer agent, wherein the polymer latex can be used for forming into a binary system in a surface active agent composition. Due to the unique crosslinking nodes in the polymer latex, the polymer latex can be used in various fields even under the low-pH and high-salt content severe environment such as the cosmetics, the medicines, the emulsion paint, and the effective and high-efficiency thickening agent and suspending agent in cleaning composition.

Description

technical field [0001] The invention relates to a polymer emulsion, in particular to an alkali-swellable polymer emulsion prepared by polymerization of one or more charged or hydrophilic monomers, which can be formed with a surface-active composition Binary system, the binary system can be used as a thickener and stabilizer for emulsions and dispersions in cosmetics, industry, and pharmaceutical compositions. Background technique [0002] Formulations based on water and solvents, such as solutions, emulsions, suspensions and suspoemulsions used in cosmetic, pharmaceutical, agricultural and industrial compositions, require thickening due to the need to improve their stability and economy. Likewise, for various aqueous detergent compositions containing silicone oil additives, abrasive or pearlescent materials, the shelf life can be significantly extended before the system components separate. At the same time, increasing the viscosity can also improve the uniform spreading of...
