Abstract: Provided are multistage polymers that comprise (i) a first stage comprising a first copolymer having a first theoretical Tg, the first copolymer being derived from a soft ethylenically-unsaturated monomer, a phosphorus-containing monomer, and an acetoacetoxy monomer; and (ii) a second stage comprising a second polymer having a second theoretical Tg, the second polymer being derived from one or more hard ethylenically-unsaturated monomers. The multistage polymers can be in the form of multilayer particles that comprise (i) a first layer comprising the first copolymer; and (ii) a second layer surrounding at least a portion of the first layer comprising the second polymer. Also provided are aqueous compositions including one or more of the multistage polymers (or multilayer particles) described herein, as well as methods for making the multistage polymers (or multilayer particles) described herein.
