Abstract: Resin compositions, layers, and interlayers comprising a poly(vinyl acetal) resin that includes residues of an aldehyde other than n-butyraldehyde are provided. Such compositions, layers, and interlayers can exhibit enhanced or optimized properties and lower VOC levels as compared to those formulated with comparable poly(vinyl n-butyral) resins.

Abstract: The present application discloses regioselectively substituted cellulose esters, films made from the regioselectively substituted cellulose esters and methods for making the same. The regioselectively substituted cellulose esters are synthesized using trifluoroacetic anhydride and cellulose with various acyl donors or acyl donor precursors.

Abstract: Processes and systems for separating a mixture including at least one fluorocarboxylic acid and at least one carboxylic acid are provided herein. In some aspects, the present invention relates to processes and systems configured to provide a purified stream of fluorocarboxylic acid and a purified stream of carboxylic acid, even when the mixture includes an azeotrope, a pinch point, and/or a eutectic mixture of the fluorocarboxylic acid and carboxylic acid. Systems as described herein may include, for example, at least one distillation zone and at least one fractional crystallization zone arranged in series and configured to provide highly purified product streams having compositions heretofore unachievable by conventional means.

Abstract: This invention relates to a rubber modified acrylic and/or vinyl resin comprising the mini-emulsion polymerization product of at least one rubber compound substantially dissolved in at least one acrylic monomer and/or vinyl monomer.

Abstract: Waterborne latexes are commonly used in a variety of coatings including architectural, industrial, paper, and many others. Many coatings would benefit from an incorporated optical whitening or brightening agent. Most common optical brighteners can not be incorporated directly into a water-based system due to their insufficient solubility in water. This report describes a technique for incorporating optical brighteners directly into a water-based latex system using a mini-emulsion polymerization process. Coatings made from these latexes exhibit significant optical whitening/brightening characteristics which greatly enhance the appearance of the coated substrate.

Abstract: A process is provided to produce an aqueous composition. The process comprises shearing a mixture to produce a mini-emulsion and polymerizing said mini-emulsion in the presence of an initiator to produce the aqueous composition; wherein said mixture comprises at least one tackifier, at least one ethylenically unsaturated monomer, at least one surfactant, and water. The aqueous composition can be utilized to produced various articles including, but not limited to, adhesives, coatings, and laminates.
