The present invention relates to a viscosity modifier represented by the following general formula (1), and an emulsion composition or an aqueous paint composition including the viscosity modifier: where: Rto Reach represent a linear alkyl group having 1 to 13 carbon atoms; Rand Reach represent a group represented by the following formula (2) or (3); m and n each represent a number from 3 to 15; x represents a number from 40 to 800; and y represents a number equal to or more than 1, provided that each of a total number of carbon atoms in Rand Rand a total number of carbon atoms in Rand Rneeds to be from 10 to 14. 

Viscosity modifier, and emulsion resin composition or aqueous coating composition each containing same

An emulsion composition according to the present invention includes: a nonionic compound having a molecular weight that is greater than or equal to 500 and a cloud point that is less than or equal to 80 degrees Celsius in a 1 percent aqueous solution in which ethylene oxide and an alkylene oxide having a carbon number that is greater than or equal to 3 are added in block and/or random form to an aliphatic alcohol having a carbon number that is less than or equal to 18; and a synthetic resin.

Emulsion composition

Disclosed are surfactants represented by the following formula (1):wherein Rrepresents a branched aliphatic hydrocarbon group, a secondary aliphatic hydrocarbon group or a branched aliphatic acyl group, AO and AO' each independently represents an oxyalkylene group having 2 to 4 carbon atoms, L represents a group represented by formula (2) to be described below, z stands for a number of from 1 to 10, X represents a hydrogen atom or an ionic hydrophilic group, m stands for a number of from 0 to 1,000, and n stands for a number of from 0 to 1,000.wherein Rand Reach independently represents a hydrogen atom or a methyl group, x stands for a number of from 0 to 12, and y stands for a number of 0 or 1. These surfactants do not contain any phenyl ether group considered to have significant effects on the environment, such as a nonylphenyl group, and have performance comparable with reactive surfactants containing one or more phenyl ether groups. Emulsifiers for emulsion polymerization, dispersants for dispersion polymerization and resin modifiers, all of which contain the surfactants, are also disclosed.
