Abstract: Polymers including multi-stage polymers that combine the structural integrity of a polymer with a high glass transition temperature (Tg) with a softer, lower molecular weight polymer that coalesces quickly and is flexible to maintain scrubbability are disclosed. Architectural compositions containing these film-forming polymers exhibit anti-blocking properties within one hour from being applied to a substrate.

Abstract: Polymers including single-stage and multi-stage polymers that combine the properties of the structural integrity of a polymer with a high glass transition temperature (Tg) with a softer, lower molecular weight polymer that coalesces quickly and is flexible to maintain scrubbability are disclosed. The single-stage or an outer stage of the multi-stage polymer contains both a cross-linking monomer and a chain transfer agent at different portions of the stage. Architectural compositions containing these film-forming polymers exhibit anti-blocking properties within one hour from being applied to a substrate.

Abstract: Disclosed herein is an additive for a paint or stain composition or for a colorant composition. The additive is polymerized from at least one acrylate monomer and a chain transfer agent. The additive has a weight molecular weight from about 2,000 Daltons to about 5,000 Daltons, and the chain transfer agent comprises a hydrogen-sulfur functionality. The additive's glass transition temperature ranges from about ?50° C. to about ?10° C. and the additive is hydrophobic.

The additive has a weight molecular weight from about 2,000 Daltons to about 5,000 Daltons, and the chain transfer agent comprises a hydrogen-sulfur functionality and is present from about 8 to about 20 parts per hundred parts of monomers. The additive's glass transition temperature ranges from about ?50° C. to about ?10° C. and the additive is hydrophobic. The additive is added to the colorant composition to minimize tip drying at the colorant canisters, and is added to paint or stain composition as an open time extender.

Abstract: Disclosed herein is a polymeric paint additive that increases the open time and the flow and leveling of paint compositions, as well as, maintaining/improving paint film properties such as scrub resistance, water sensitivity, surfactant leaching and stain removal. The polymeric open time additive preferably has a high glass transition temperature, e.g., above 100° C., as determined by the well-known Fox's equation, and molecular weight of less than 20,000 Daltons (number average molecular weight). The particle size of the inventive polymeric open time additive is in the range of about 130 nm to about 230 nm (volume average), prior to being dissolved in a basic solution, such as an aqueous architectural composition.
