Emulsion including acrylic polymer particles and related processes

Abstract

An emulsion includes water, an emulsifier, and acrylic polymer particles dispersed in the water. The acrylic polymer particles include monomer units of an alkyl acrylate, alkyl methacrylate, or combination thereof, in which alkyl has at least eight carbon atoms; at least one percent by weight acid-functional monomer units, based on the total weight of the monomer units in the acrylic polymer particles; monomer units of a high Tg monomer comprising at least one of t-octyl acrylamide, t-butyl methacrylate, t-butyl acrylate, isobornyl acrylate, or isobornyl methacrylate; and a chain terminal group having at least four carbon atoms and a thioether group. In some embodiments, the emulsion provides an adhesive able to hold a pinch bond in a foam cube within one minute of spraying the emulsion. A process for making the composition and a process for making a bonded article using the composition are also described.
