Abstract:
The present invention relates to a latex composition containing polymer particles that are polymerized in at least two stages including a first phase polymer having a relatively high molecular weight and a relatively high glass transition temperature, and a second phase polymer having a relatively low molecular weight, a relatively high glass transition temperature, and polymerized from constituent monomers that include a crosslinkable monomer. Paint compositions and architectural coatings containing the latex composition according to the invention are also described herein, as well as substrates coated therewith.
