Summary:PROBLEM TO BE SOLVED: To obtain a surfactant which exhibits a remarkable effect on lowering interfacial tension and is excellent in emulsion stability by incorporating an amphiphatic partly quaternized vinylpyridine polymer into the same. SOLUTION: This vinylpyridine polymer is represented by the formula (R is alkyl; X is halogen, esp. chlorine, bromine, or iodine; n is 4-30; and x is 0.5-15) and is produced by polymerizing a vinylpyridine compd. (e.g. 4- or 2- vinylpyridine) in the presence of an alkanethiol (e.g. dodecanethiol) as the telogen and quaternizing the resultant vinylpyridine telomer with an alkyl halide (e.g. lauryl bromide). The interfacial chemical characteristics of the polymer depend on the degree of polymn. and the number of alkyl chains. When the degree of polymn. is 10, then the polymer having 2 or 3 alkyl chains is excellent in the capability for lowering interfacial tension; when the degree of polymn. is 19, then one having 4 or 5 alkyl chains is excellent.
