Abstract: A modulating refrigeration system includes an evaporation unit and a condensing unit. The evaporation unit generates a first output airflow comprising a lower temperature, a lower relative humidity, or both than a first supply airflow and directs the first output airflow into a building. The condensing unit generates a second output airflow at a higher temperature than a second supply airflow and discharges the second output airflow to an unconditioned space. The evaporation unit comprises a first valve operable to direct a portion of refrigerant to a secondary evaporator and primary evaporator or to direct the entire flow of refrigerant to the primary evaporator and bypassing the secondary evaporator.

Abstract: Water-dispersible or water-dispersed polymers are made by reacting (i) an unsaturated monomer containing one or more cyclic carbonate groups, or (ii) an unsaturated or saturated oligomer or polymer containing a plurality of cyclic carbonate groups, with a tertiary amine in the presence of an acid, or with an acid in the presence of a tertiary amine, or in the presence of an acid and a tertiary amine, to provide a water-dispersible or water-dispersed monomer, oligomer or polymer. When step a) provides a monomer or oligomer, the monomer or oligomer is reacted with one or more monomers in the presence of an initiator to provide a water-dispersible or water-dispersed polymer. When step a) provides a polymer, the polymer is optionally used to support emulsion polymerization of one or more unsaturated monomers in the presence of an initiator to provide a water-dispersible or water-dispersed further polymer.

Abstract: An aqueous coating composition is provided that is preferably substantially free of styrene and structural units derived from styrene.

The resin system is preferably formed using a process that includes emulsion polymerizing the ethylenically unsaturated monomer component in the presence of an aqueous dispersion including the water-dispersible polymer. In certain preferred embodiments, the water-dispersible polymer is a salt of an acid- or anhydride-functional aromatic polyether polymer.
