1. A method comprising:
a) forming a pre-emulsion by combining a monomer composition with a siloxane-containing composition in water, the monomer composition including one or more monomers selected from the group consisting of (meth)acrylic acid monomers, (meth)acrylic monomers, vinyl functional monomers, and combinations thereof; and
b) polymerizing the pre-emulsion by combining the pre-emulsion with a radical initiator in a reactor to form a reaction mixture that polymerizes into an emulsion polymer,
wherein the siloxane-containing composition includes a siloxane having structure 1, 2, or 3:
