Title:
SURFACTANT COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2015/001968
Kind Code:
A1
Abstract:
A surfactant composition containing one or more reactive surfactants (X) represented by general formula (I) and one or more polyfunctional compounds (Y) represented by general formula (II) (in the formulae, D represents a polymerizable unsaturated group represented by formula (D-1) or (D-2); R1 represents a hydrogen atom or a methyl group; A represents an alkylene group having 2-4 carbon atoms or a substituted alkylene group; each of n1 and n2 represents the mole number of added groups, which is a number of 0-1,000; T represents a hydrogen atom or a specific anionic hydrophilic group; m1 represents the number of substituents, which is a number of 1-2; m2 represents the number of substituents, which is a number of 1-3; and m3 represents the number of substituents, which is a number of 2-3) suppresses foaming of an emulsion or dispersion. For example, in cases where this surfactant composition is used as an emulsifying agent for emulsion polymerization, this surfactant composition exhibits high polymerization stability and is capable of improving various characteristics such as water resistance of a coating film.
