A polymer emulsion is produced by the free radical polymerization of a monomer having an ethylenic unsaturated double bond in the presence of 0.1 to 10 wt parts of a compound having the formula <IMAGE> wherein R1 represents hydrogen atom or methyl group; R2 represents hydrogen atom, methyl or ethyl group; R3 represents an alkyl group having 6 to 22 carbon atoms; n is 1, 2, or 3; and X represents a halogen atom, per 100 wt parts of the monomer. |
