    摘要： Provided is a reactive emulsifier for emulsion polymerization, capable of enhancing stability during emulsion polymerization, avoiding a processing trouble by reducing foaming in a polymer dispersion, and improving the properties such as water resistance of a polymer film obtained from the polymer dispersion. An emulsifier for emulsion polymerization containing a compound represented by the following general formula (I) is used. In the general formula (I), R 0 represents an alkyl group having 1 to 4 carbon atoms, R 1 represents one or two types of groups selected from the groups shown below, R 2 represents hydrogen or a methyl group, D represents a polymerizable unsaturated group represented by the chemical formula D-1 or D-2 shown below, R 3 represents a hydrogen atom or a methyl group, m1 represents a number of 1 to 2, m2 represents a number of 1 to 4, m3 represents a number of 0 or 1, A represents an alkylene group or a substituted alkylene group having 2 to 4 carbon atoms, n represents an average addition mole number of alkylene oxide and represents a number in the range of 0 to 1,000, X represents a hydrogen atom or an anionic hydrophilic group selected from -(CH 2 ) a -SO 3 M, -(CH 2 ) b -COOM, -PO 3 M 2 , -P(Z)O 2 M, and -CO-CH 2 -CH(SO 3 M)-COOM, wherein a and b each represent a number of 0 to 4, Z represents a residue obtained by removing X from the general formula (I), and M represents a hydrogen atom, an alkali metal atom, an alkaline earth metal atom, an ammonium residue, or an alkanolamine residue.
