Zusammenfassung:To provide a resin emulsion that is excellent in polymerization stability, water resistance and heat resistance, and an emulsifier for emulsion polymerization that is used for obtaining the resin emulsion.SOLUTION: An emulsifier for emulsion polymerization contains a surface active agent (X) represented by general formula (1): R-OCOCH | R-OCOCH-SO(M). In general formula (1), in Rand R, one is an alkyl group having 8 to 18 carbon atoms, and the other is a methallyl group; and (M)represents an alkali metal ion (in this case, M represents alkali metal, and n represents 1), an alkali earth metal ion (in this case, M represents alkali earth metal, and n represents 2) or ammonium (in this case, M represents NH, and n represents 1).SELECTED DRAWING: None 【課題】 本発明は重合安定性、耐水性、耐熱性に優れた樹脂エマルション及び前記の樹脂エマルションを得るために用いる乳化重合用乳化剤を提供することを目的とする。【解決手段】 下記一般式(1)で表される界面活性剤(X)を含有する乳化重合用乳化剤。R1−OCOCH|R2−OCOCH−SO3−(Mn+)1/n(1)[一般式(1)中、R1及びR2の内、一方は炭素数8〜18のアルキル基、他方はメタリル基であり;(Mn+)1/nはアルカリ金属イオン(この場合、Mはアルカリ金属を表し、nは1を表す)、アルカリ土類金属イオン(この場合、Mはアルカリ土類金属を表し、nは2を表す)又はアンモニウム(この場合、MはNH4を表し、nは1を表す)であることを表す。]【選択図】なし
