本発明は水性樹脂分散体用乳化剤に関し，ＰＦにエチレ
ン性不飽和単量体の水系乳化重合に用いる新規、かつ有
用な乳化剤に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an emulsifier for aqueous resin dispersions, and more particularly to a novel and useful emulsifier for use in aqueous emulsion polymerization of ethylenically unsaturated monomers in PF.
従来、乳化重合用乳化剤としては、アルキル硫酸エステ
ル塩、アルキルベンゼンスルホン酸塩、ジアルキルスル
ホコハク酸エステル塩、ポリオキシアルキレンアルキル
（アリール）エーテル硫酸エステル塩等の７ニオン性界
面活性剤、ポリオキシアルキレンアルキル（アリール）
エーテル、ポリオキシエチレンポリオキシプロピレンブ
ロック共重合体、ポリオキシエチレンソルビタン脂肪酸
エステル等の非イオン性界面活性剤が，単独あるい性、
またエマルジョンから製造されたフィルムの性質等は、
かならずしも充分に満足し得るものでなく、多くの解決
すべき問題点が残されている。Conventionally, emulsifiers for emulsion polymerization include 7-ionic surfactants such as alkyl sulfate salts, alkylbenzene sulfonate salts, dialkyl sulfosuccinate salts, polyoxyalkylene alkyl (aryl) ether sulfate salts, polyoxyalkylene alkyl ( aryl)
Nonionic surfactants such as ether, polyoxyethylene polyoxypropylene block copolymer, and polyoxyethylene sorbitan fatty acid ester may be used alone or in combination.
In addition, the properties of the film produced from the emulsion are as follows:
The results are not always completely satisfactory, and many problems remain to be solved.
即ち、エマルジョンの重合安定性、得られたエマルジョ
ンの機械安定性、化学安定性、凍結融解安定性、顔料混
和性、貯蔵安定性等に問題があり。That is, there are problems with the polymerization stability of the emulsion, the mechanical stability, chemical stability, freeze-thaw stability, pigment miscibility, storage stability, etc. of the emulsion obtained.
特に、機械安定性については、改善すべき問題点が残さ
れている。In particular, problems remain that need to be improved regarding mechanical stability.
さらに、エマルジョンからポリマーフィルムを製造した
際、使用した乳化剤がＴｔ敲の状態でポリマーフィルム
に残るため、フィルムの耐水性、接着性が劣る等の問題
を生じてしくる。Furthermore, when a polymer film is produced from an emulsion, the emulsifier used remains in the polymer film in a Tt-like state, resulting in problems such as poor water resistance and adhesive properties of the film.
また、エマルジョンを塩析等の手段によって破壊しポリ
マーを取り出すとき、排水中に多くの乳化剤が含有され
、河川汚濁の原因となるだめ、乳化剤の除去処理に多大
の労力が必要となる。Furthermore, when the emulsion is destroyed by means such as salting out to extract the polymer, a large amount of emulsifier is contained in the wastewater, which causes river pollution, and requires a great deal of effort to remove the emulsifier.
このような観点から、従来の乳化剤の問題点を解決する
ため数多くの一般に反応性乳化剤といわれる新規乳化剤
に関する特許が提案されている。From this point of view, a number of patents relating to new emulsifiers, generally referred to as reactive emulsifiers, have been proposed in order to solve the problems of conventional emulsifiers.
