Application of Ammonium α-Allyl Alkyl Phenol Polyoxyethylene Ether Sulfonate in Acrylic Emulsion Pressure-Sensitive Adhesive

Three acrylic pressure-sensitive adhesives with same composition but emulsified by different surfactants were prepared. The test results showed that adhesion properties and water resistance of the adhesives emulsified by polymerizable surfactant were better than those of conventional ones. In addition, surface tension and contact angle of adhesive based on polymerizable surfactant were higher than the conventional ones. These differences were attributed to the different migration abilities of the surfactants, as explained with atomic force microscopy images. Furthermore, the storage modulus of the adhesive can be enhanced by the reaction of polymerizable surfactant, which was conformed by dynamic mechanic analysis.
