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.
