This disclosure relates to barrier compositions. The barrier composition can comprise a copolymer formed by polymerizing monomers comprising derived from a vinyl aromatic monomer and a second monomer selected from the group consisting of butadiene alkyl (meth)acrylates and mixtures thereof, and a solid grade oligomer. In some embodiments, the vinyl aromatic monomer and the second monomer are polymerized in the presence of the solid grade oligomer. Paper products and methods of making the paper products comprising the barrier composition are also described herein. The barrier compositions disclosed herein can be used to impart water, moisture, grease, oil, and/or oxygen resistance to the paper product. |
