Abstract:
Disclosed are surfactants represented by the following formula (1): wherein R represents 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 R and R each 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.

Abstract:
An object of the present invention is to provide an emulsion resin composition containing a urethane-type viscosity modifier which does not cause an increase in product viscosity of the emulsion resin composition even if the emulsion resin composition is stored at high temperature or low temperature for a long period of time, or an aqueous resin composition. In order to achieve the object of the present invention, the present invention provides a viscosity modifier represented by the following general formula (1) , and an emulsion composition or an aqueous paint composition including the viscosity modifier: where: R 1 to R 4 each represent a linear alkyl group having 1 to 13 carbon atoms; R 5 and R 6 each 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 R 1 and R 2 and a total number of carbon atoms in R 3 and R 4 needs to be from 10 to 14.
