Abstract: Disclosed are aromatic enol ethers that have utility as film-hardening additives for coating formulations. The aromatic enol ethers have particular utility as film-hardening additives for water-based coating formulations. The aromatic enol ethers provide improvements in hardness and hardness related properties such as block resistance without contributing to the volatile organic content of the composition.

Abstract: A bale of sheets made of virgin cellulose fibers and cellulose ester (CE) staple fibers can be fed to a hydropulper. The CE staple fibers have: i. a denier per filament (DPF) of less than 3, or ii. a cut length of less than 6 mm, or iii. crimping, or iv. a combination of any two or more of (i)-(iii). The bales can be fed and dropped in as entire bales to a hydropulper, or a blend tank directly or indirectly in fluid communication with a hydropulper, using the same feed system employed for feeding cellulose to the hydopulper and avoiding having to defiberize by pulling or drawing fibers from a box container into a hydropulper.

Abstract: Pre-ground plastics of small particle size not more than 2 mm are co-fed into a solid fossil fuel fed entrained flow partial oxidation gasifier. A syngas composition can be made by charging an oxidant and a feedstock composition comprising recycle plastics and a solid fossil fuel to a gasification zone within a gasifier; gasifying the feedstock composition together with the oxidant in said gasification zone to produce said syngas composition; and discharging at least a portion of said syngas composition from said gasifier; wherein the recycled plastics are added to a feed point comprising a solid fossil fuel belt feeding a grinder after the solid fossil fuel is loaded on the belt, a solid fossil fuel belt feeding a grinder before the solid fossil fuel is loaded onto the belt, or a solid fossil fuel slurry storage tank containing a slurry of said solid fossil fuel ground to a size as the size fed to the gasification zone.

Abstract: A copolyester resin composition is described. The copolyester resin composition includes a linear copolyester polymer and a linear copolyester oligomer. A particularly suitable linear copolyester oligomer is an intermediate of the copolyester polymer. The composition exhibits improved melt flowability and is therefore particularly useful in the manufacture of products made via injection molding methods. A process for forming the composition is also described.

Abstract: The present invention relates to plasticizer compositions comprising a glycol ether, a dialkyl ether, or glycol ether ester; and certain plasticizers, which offer superior performance in blends containing polyvinyl chloride (PVC) resins. The plasticizer compositions of the present invention can effectively reduce viscosity and fusion temperature of PVC plastisols, and are particularly useful as viscosity control additives in plasticized PVC formulations.

Abstract: This invention relates to aliphatic, carbamate-functional polyester resins for use in coatings. More particularly this invention relates to aliphatic, carbamate-functional polyester resins containing 2,2,4,4-tetramethyl-1,3-cyclobutanediol (TMCD) that exhibit improved scratch resistance and acid etch resistance when formulated into 2K automotive clearcoats. These carbamate-functional polyesters can be used as the sole resin in the clearcoat binder or in combination with other carbamate-functional acrylic resins and/or hydroxyl-functional acrylic and polyester resins.

Abstract: Polar silane linkers are provided that attach to resins to form silane-functionalized resins. The functionalized resins can be bound to hydroxyl groups on the surface of silica particles to improve the dispersibility of the silica particles in rubber mixtures. Further disclosed are synthetic routes to provide the silane-functionalized resins, as well as various uses and end products that benefit from the unexpected properties of the silane-functionalized resins. Silane-functionalized resins impart remarkable properties on various rubber compositions, such as tires, belts, hoses, brakes, and the like. Automobile tires incorporating the silane-functionalized resins are shown to possess excellent results in balancing the properties of rolling resistance, tire wear, and wet braking performance.
