Described herein is an aqueous composition to improve barrier properties. Particularly, described herein is a polymer-based grease resistant aqueous composition for coating paper and paper products.

Aqueous compositions with improved barrier properties

Described herein is a multi-phase polymer binder including an aqueous polymer dispersion, an optional hydrophobic emulsion, and an optional surfactant. The polymer binder, when dried, provides a water uptake of less than about 5 g/m/20 min, a seal strength of at least about 200 Newton/meter (N/m) as measured at 25&#xb0; C. or at 90&#xb0; C., and sufficient block resistance to impart no substrate damage.

Aqueous water barrier coatings

A copolymer includes a hydrophobic head segment and a random copolymer tail segment comprising hydrophobic blocks and ionizable blocks. Emulsion polymerization systems incorporate the copolymer as a surfactant.

Hydrophobic block&#x2014;random block copolymer emulsion polymer stabilizers

Described is an aqueous composition comprising (a) at least one polyanion, (b) at least one ethoxylated cationic polymer, and (c) at least one phyllosilicate. The composition can be used for providing oxygen barrier properties to a polymer film.

Compositions containing polyanion, ethoxylated cationic polymer and phyllosilicates for improved oxygen barrier coatings

Styrene-acrylic dispersants for use in pigment dispersions have lower viscosities than benchmark formulations such as nitrocellulose, dimer-acid based polyamides, and thermoplastic polyurethanes, prepared under otherwise identical conditions. Lower viscosities allow for the preparation of similarly viscous dispersions and inks with the styrene-acrylics when compared to traditional dispersants, at either (a) lower solvent levels, or if solvent levels are to be maintained, (b) higher pigment and solids loadings.

Low VOC solvent-borne printing inks

Methods for forming high molecular weight chain-extended condensation polymers are disclosed. The methods include adding a chain extender during the polymerization process of a condensation polymer to provide a chain-extended condensation polymer, wherein the chain extender comprises a polymerization product of at least one epoxy-functional (meth)acrylic monomer, and at least one styrenic and/or (meth)acrylic monomer.

Process for the production of condensation polymers via in-reactor chain extension and products thereof

Oligomer-modified anionically polymerized polymers, reinforced materials made with the polymers and articles made from the reinforced materials are provided. The oligomer-modified polymers are made by reacting anionically polymerized polymers with low molecular weight acrylic oligomers. The oligomer-modified polymers may be used as adhesives, compatibilizers, reinforcing agents and impact modifiers.

Modified anionically polymerized polymers

The invention provides chain extenders made from epoxy-functional (meth)acrylic monomers and styrenic and/or (meth)acrylic monomers. The invention further provides polymeric compositions made from the chain extenders and plastic articles made from the compositions. Finally, the invention provides methods of using the chain extenders to improve the properties of virgin, recycled, and reprocessed condensation polymers.
