    • Disclosed are surfactants represented by the following formula (1): wherein R1 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 R2 and R3 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.
