Abstract: A polyacrylamide-based AMPS (2-acrylamido-2-methylpropane sulfonic acid) copolymer or terpolymer emulsion system may comprise 5-50% solid AMPS salt by weight of a polymer backbone in an emulsion polymerization, wherein use of solid AMPS salt reduces a total amount of water in the emulsion system. The polymer concentration may be above 35% by weight and the water concentration is below 31% by weight. Solid AMPS salt may be dissolved in acrylamide 50% solution, either with or without monomers, to control the total amount of water in an emulsion that may be formed, particularly to lower the water concentration. Use of solid AMPS salt dissolved in acrylamide 50% solution may introduce the AMPS monomer into an emulsion system without requiring addition of extra water. This may improve performance on the polymer backbone as well as the finished emulsion system.

Abstract: A structure is generally described which may be effective to store and/or display a product. The structure may include a top, a bottom, a left side, a right side and a back. The top and bottom may be the same dimensions. The left side and right side may be the same dimensions and a shorter length than the top and bottom. The left side, right side, and back may be secured to the bottom and to the top so as to form a structure with edges from the top, the bottom, the left side and the right side aligned with the back. The structure may define a storage area within the space enclosed by the top, the bottom, the left side, the right side and the back. The structure may define a display area between the top and the bottom that extends past the left side and the right side.
