Abstract
A method for forming an acrylic emulsion includes a step of forming pre-emulsion by combining a monomer composition with an amphoteric surfactant in water and then polymerizing the pre-emulsion by combining the pre-emulsion with a radical initiator in a reactor to form a reaction mixture. The monomer composition includes one or more monomers selected from the group consisting of (meth)acrylic acid monomers and (meth)acrylic monomers, and combinations thereof. An acrylic emulsion formed by the method is also provided.
