A reactive emulsifier for emulsion polymerization, which is capable of making polymerization stability good, reducing foaming to avoid a process trouble, and further conspicuously improving various properties of a polymer film, such as water resistance, adhesion, heat resistance, weather resistance, etc., is provided. An emulsifier for emulsion polymerization including a compound represented by the following general formula (I) is used.
X = H, -(CH 2 ) a -SO 3 M, -(CH 2 ) b -COOM, -PO 3 M 2 , -P(B)O 2 M, or -CO-CH 2 -CH(SO 3 M)-COOM
Y = Z = In the general formula (I), R 1 represents an alkyl group having from 1 to 4 carbon atoms; R 2 represents a hydrogen atom or a methyl group; X represents a hydrogen atom or a group selected from the foregoing anionic hydrophilic groups; Y represents a group selected from substituents represented by the foregoing structural formulae, a substitution number of which is any one of from 1 to 3, and in the structural formulae representing these substituents, R 2 represents a hydrogen atom or a methyl group; Z represents a polymerizable unsaturated group represented by the foregoing structural formula, and in the structural formula representing this unsaturated group, R 3 represents a hydrogen atom or a methyl group; each of A 1 and A 2 represents an alkylene group or a substituted alkylene group each having from 2 to 4 carbon atoms, or a residue derived from an alkyl glycidyl ether or an alkenyl glycidyl ether each having from 4 to 22 carbon atoms; 1 represents a number of from 0 to 5; m represents a number of from 1 to 2; and n represents a number from 0 to 100. |
