A high performance wall assembly receives an exterior covering of a building. The high performance wall assembly includes a frame assembly having a top member, a bottom member opposite the top member, and a plurality of vertical members. The vertical members are coupled to and extend between the top and bottom members. The high performance wall assembly also includes a rigid foam insulating panel coupled to the frame assembly. A structural foam layer is disposed on the plurality of vertical members and on the rigid foam insulating panel. The structural foam layer couples the rigid foam insulating panel to the frame assembly and couples the plurality of vertical members to the top and bottom members such that the high performance wall is free of fasteners.

Provided are multistage polymers that comprise (i) a first stage comprising a first copolymer having a first theoretical T, 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 T, 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.

A prefabricated wall assembly receives an exterior covering of a building. The prefabricated wall assembly comprises a frame assembly and an outer foam layer. The outer foam layer is coupled to the frame assembly. The outer foam layer extends from the frame assembly to an exterior surface of the outer foam layer. The exterior surface of the outer foam layer is configured to receive the exterior covering of the building. The outer foam layer comprises a plurality of particles and a binder that define a plurality of pathways. The pathways extend vertically through the prefabricated wall assembly from the top member to the bottom member of the frame assembly for allowing airflow and drainage between the frame assembly and the exterior covering.
