A multistage emulsion polymer comprising a first polymer and a second polymer comprising structural units of a nitrogen-containing heterocyclic monomer at specific weight ratios of the first polymer to the second polymer and a Tg difference between the first and second polymers; the multistage emulsion polymer suitable for use in coating applications to provide coating films with improved dirt pick-up resistance without compromising film formation properties.

Multistage emulsion polymer and process of preparing the same

An aqueous dispersion of polymeric particles comprising a specific emulsion polymer and a hydroxyl-terminated polysiloxane, and an aqueous coating composition comprising the aqueous dispersion providing coatings made therefrom with improved water resistance, anti-corrosion, and water repellency properties.

Aqueous dispersion of polymeric particles

An aqueous dispersion of multistage polymer particles comprising a specific oligomer prepared from polymerization of monomers comprising an alkoxylated (meth)acrylate providing aqueous coating compositions with both good flow-and-leveling property and extended open time.

Aqueous dispersion of multistage polymer particles and process of making the same

A polyurethane/acrylic hybrid dispersion comprising a polyurethane dispersion, acrylic monomers and ethylenically unsaturated phosphorus containing monomers. The weight ratio of the solid content of the polyurethane dispersion to the acrylic monomers and the ethylenically unsaturated phosphorus containing monomers is from 3:7 to 7:3. A process of making the polyurethane/acrylic hybrid dispersion.
