Abstract
Composition and methods of making the compositions are provided. The composition may include an aqueous emulsion of a polymer resin and a hydrophobic monomer with the proviso that the composition is surfactant-free; wherein the support resin may be a styrene-acrylic resin or acrylic resin having from about 5 wt % to about 40 wt % acid functional repeat units.

A composition comprising an aqueous emulsion of a support resin and a polymer of a hydrophobic monomer, with the proviso that the composition is surfactant-free;
- wherein:
- the support resin is a styrene-acrylic resin or acrylic resin having from about 5 wt % to about 40 wt % acid functional repeat units;
- and
- the polymer of the hydrophobic monomer consists of hydrophobic monomers selected from the group consisting of heneiscosyl acrylate, behenyl acrylate, lignoceryl acrylate, heptacosanyl acrylate, montanyl acrylate, nancosanyl acrylate, myricyl acrylate, dotriacontyl acrylate, geddyl acrylate, heneiscosyl methacrylate, behenyl methacrylate, lignoceryl methacrylate, heptacosanyl methacrylate, montanyl methacrylate, nancosanyl methacrylate, myricyl methacrylate, dotriacontyl methacrylate, geddyl methacrylate, and a combination of two or more thereof.
A composition comprising an aqueous emulsion of a support resin and a polymer of a hydrophobic monomer, with the proviso that the composition is surfactant-free;
- wherein:
- the support resin is a styrene-acrylic resin or acrylic resin having from about 5 wt % to about 40 wt % acid functional repeat units;
- the support resin has been post-modified with a support resin hydrophobic monomer;
- and
- the polymer of the hydrophobic monomer consists of hydrophobic monomers selected from the group consisting of heneiscosyl acrylate, behenyl acrylate, lignoceryl acrylate, heptacosanyl acrylate, montanyl acrylate, nancosanyl acrylate, myricyl acrylate, dotriacontyl acrylate, geddyl acrylate, heneiscosyl methacrylate, behenyl methacrylate, lignoceryl methacrylate, heptacosanyl methacrylate, montanyl methacrylate, nancosanyl methacrylate, myricyl methacrylate, dotriacontyl methacrylate, geddyl methacrylate, and a combination of two or more thereof.
A composition comprising an aqueous emulsion of a post-modified support resin comprising a support resin and a homopolymer of a hydrophobic monomer, with the proviso that the composition is surfactant-free;
- wherein:
- the support resin is a styrene-acrylic resin or acrylic resin having from about 5 wt % to about 40 wt % acid functional repeat units,
- the support resin is post-modified with lauryl glycidyl ether, stearyl glycidyl ether, or a mixture thereof to provide a post-modified support resin, and the homopolymer of the hydrophobic monomer is grafted to the post-modified support resin;
- and
- the homopolymer of the hydrophobic monomer consists of hydrophobic monomers selected from the group consisting of heneiscosyl acrylate, behenyl acrylate, lignoceryl acrylate, heptacosanyl acrylate, montanyl acrylate, nancosanyl acrylate, myricyl acrylate, dotriacontyl acrylate, geddyl acrylate, heneiscosyl methacrylate, behenyl methacrylate, lignoceryl methacrylate, heptacosanyl methacrylate, montanyl methacrylate, nancosanyl methacrylate, myricyl methacrylate, dotriacontyl methacrylate, and geddyl methacrylate.
