摘要： Herein, we enable a record-high FDCA reaction rate of 416 μmol h-1 cm-2 (1872 μmol h-1) at 100% FDCA selectivity using a ZnCo2O4 electrocatalyst in a near-neutral media that allows high concentration (i.e. 1M) of HMF, with assistance of an in-situ alkaline modification strategy that further enhances the reaction rate. In the light of the significantly improved FDCA production, we demonstrate production of PEF bioplastic from a biomass-derivative fructose, highly competitive to the petroleum-based production of PET plastics as indicated by our techno-economic analysis.

摘要： Provided is a resin containing a polybutylene succinate sebacate, characterized in that a content of an alkali metal is 0.001 mass ppm or more and 6.0 mass ppm or less. According to the present invention, it is possible to provide a polyester resin, a resin composition and a shaped object which achieve both biodegradability in seawater and hydrolysis resistance, which are contradictory properties, at high level.

摘要： In one or more embodiments, the present invention provides am method of making a poly(propylene fumarate-co-succinate) (PPFS) copolymer containing a random incorporation of succinate groups and targetable reduction profiles without the need for three or more monomer units. To achieve this, a time-dependent sonication-promoted zinc/acetic acid reduction of the PPM unsaturated double bonds has been used to create a random PPMS copolymer which may be isomerized into the PPFS equivalent. By changing the sonication time as well as the ratios of acetic acid, zinc, and PPM unsaturated alkenes, partial reduction of the PPM alkenes has been shown to give PPMS products containing varying compositions of succinic and maleate units, which may then be isomerized to the PPFS product.

摘要： Provided are a liquid crystal polymer film (LCP film) and a laminate comprising the same. The LCP film has a first surface and a second surface opposite each other, and the first surface has an arithmetical mean height of a surface (Sa) less than 0.32 μm. The LCP film with proper Sa is suitable to be stacked with a metal foil, such that a laminate comprising the LCP film can have an advantage of low insertion loss.

摘要： An alkyd polymer composition for fast-drying, low VOC applications is provided. The alkyd polymer incorporates a minimum required level of a cyclic ether- and hydroxyl-containing composition formed from a sugar alcohol during the alcoholysis step while synthesizing the alkyd polymer. The disclosure also relates to the cyclic ether- and hydroxyl-containing composition which must have a minimum required level of cyclic ether structure incorporated therein in order to produce a sufficiently fast-drying alkyd polymer. Methods of making the cyclic ether- and hydroxyl-containing composition and the alkyd polymer comprising, as polymerized units, the cyclic ether- and hydroxyl-containing composition and a poly acid and/or an anhydride compound, as well as an optional polyol, other than the sugar alcohol, are also provided. Also provided is a 13 C NMR method of characterizing the necessary minimum required level of cyclic ether ring structure in the cyclic ether- and hydroxyl-containing composition and the alkyd polymer formed therefrom.
