Abstract
The present invention relates to a latex prepared from functional monomers M1 and M2, with improved reaction stability and storage stability. In addition, the present invention further relates to an aqueous coating composition prepared from the same, which has improved freeze thaw stability while maintains wet scrub resistance, particularly substantially free of freeze-thaw additives.
