Emulphor OPS 25 Octylphenol polyglycol ether sulphate sodium salt BASF Dispersing agents >> Surfactants-like Emulsifier Acrylic/Acrylate Resins Vinyl Coatings >> Waterborne General Industrial /Maintenance Emulphor® types. Ionic emulsifiers. The Emulphor grades are high-molecular-weigth ether sulphates which are preferentially used in the emulsion polymerization of acrylate and methacrylate esters, styrene and vinyl esters. They can be used in homopolymerization as well as in copolymerization of these monomers. These anionic emulsifiers are also combined with nonionic Emulan grades in order to achieve the desired properties such as particle size or emulsion stability.
