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 comprising a multistage polymer comprising a first polymer and a second polymer that comprises structural units of an ethylenically unsaturated siloxane monomer, the multistage polymer comprising, by weight based on the weight of the multistage polymer, 4.5% or more of structural units of the ethylenically unsaturated siloxane monomer, and the coagulum content of the aqueous dispersion is less than 2,000 ppm after filtration through a 44 micron sieve.
