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.
