Abstract: A polyester including ethylene 2,5-furandicarboxylate units is prepared in a process, where in an esterification step a 2,5-furandicarboxylate compound is reacted with ethylene glycol to form an ester composition, including components with 2-hydroxyethyl and 2,5-furandicarboxylate moieties; where in a polycondensation step the ester composition thus obtained is subjected to polycondensation at reduced pressure in the presence of a polycondensation catalyst to obtain a polycondensate; and where during the polycondensation step 2,5-furandicarboxylic acid is added to the ester composition.

Abstract: Disclosed are aliphatic-aromatic biodegradable polyesters obtained from aliphatic dicarboxylic acids, polyfunctional aromatic acids of renewable origin and particularly 2,5-furan dicarboxylic acid, and diols. Also disclosed are blends of the polyesters with other biodegradable polymers of either natural or synthetic origin. The polyesters have properties and viscosity values that make them suitable, after adjusting their molecular weight, for use in numerous practical applications such as films, injection molded products, extrusion coatings, fibers, foams, thermoformed products, extruded profiles and sheets, extrusion blow molding, injection blow molding, rotomolding, stretch blow molding.

Abstract: Disclosed herein is a method for removing nitrogen from water, which makes it possible to omit equipment for controlling the supply of a carbon source (hydrogen donor), equipment for post-processing a carbon source (hydrogen donor), and circulation equipment and to prevent an increase in the size of a system. The method includes adding a solid material containing a biodegradable resin as a hydrogen donor to one water system in which bacteria cells having an ability to decompose a biodegradable resin, bacteria cells having nitrification capabilities, and bacteria cells having denitrification capabilities live together to allow a nitrification reaction and a denitrification reaction coexist in the water system. Also disclosed herein is a nitrification-reaction promoting agent for water treatment including 20 wt % or more of a biodegradable resin and having a specific gravity of more than 1 g/cm3.

Abstract: A wearable device including a body having one or more embedded electronic components, the body further including a thermoset material having a polymeric backbone with at least one urethane linkage and a glass transition temperature. At a first temperature that is lower than the glass transition temperature, the body has an original shape. When the body is heated to a second temperature that is higher than the glass transition temperature, the body is deformable from the original shape to a first shape and when the body is cooled to a third temperature that is lower than the glass transition temperature, the first shape is maintained. The body is further configured to transition from the first shape to the original shape when the body is heated from the third temperature to a fourth temperature that is higher than the glass transition temperature.

Abstract: This invention pertains to a curable composition comprising a first component having beta-ketoacetate and/or malonate functionalities and a second component having two or more aldehyde functionalities. The compositions can be cured at room temperature or low temperatures to yield crosslinked networks that are capable of providing desirable properties for coating and adhesive applications. The reactive functionalities of beta-ketoacetate, malonate, and aldehyde can be either on polymers as the main binders or on small molecules as the crosslinkers. The curable compositions desirably are either solventless or organic solvent based.
