式中、W1、W2、W3・・・Wnは、不飽和単量体組成物に対する各不飽和単量体の割合(重量%)であり、T1、T2、T3・・・Tnは、各不飽和単量体の単独重合体のガラス転移温度(絶対温度(K))である。ここで、各不飽和単量体の単独重合体のガラス転移温度は、Polymer Hand Book(Second Edition, J. Brandrup・E. H. Immergut 編)による値である。
ラジカル反応性界面活性剤の使用量は、使用する不飽和単量体組成物に対して、0.5重量%~5重量%であることが好ましい。ラジカル反応性界面活性剤の使用量が少な過ぎると重合安定性が低下する場合があり、一方、多過ぎると耐水性が低下する場合がある。これらのラジカル反応性界面活性剤は、基本的に不飽和単量体を乳化させる目的で乳化重合前或いは乳化重合中に添加することが必須であるが、乳化重合後のエマルジョンに安定性を付与する目的で後添加してもよい。
