    摘要： In the invention, highly pure crystals of difructose dianhydride III (di-D-fructofuranose-1,2′:2,3′-dianhydride; hereinafter referred to as DFA III) are produced by adding 5% or less of powdered active carbon to a DFA III containing purified solution containing DFA III of 90% or more purity at a concentration of R-Bx 10-60, preferably 40-55, and after stirring, applying the mixture to solid-liquid separation (filtration with diatomaceous, filtration through a membrane filter, ultrafiltration, or continuous centrifugal separation) and concentrating the separated liquid part, followed by immediate crystallization.In the process of the invention, DFA III crystals can be produced efficiently and industrially, and the resulting crystals can be used for various purposes in pharmaceuticals or food and drink since they have no smell. This is characteristics of the invention different from the prior art products.

    摘要： A tetrafluoroethylene copolymer comprising 30 to 81 mole % of tetrafluoroethylene and a 70 to 19 mole % of at least one other monomer, and having terminal carbonate groups at polymer chain ends, which has a melt flow rate of 0.1 to 100 g/10 min. at 200° C. under a load of 5 kg, and a melting point of 90 to 200° C. This copolymer can be firmly adhered directly to other materials such as general-purpose resins while maintaining the good properties of fluororesins such as chemical resistance, weather resistance, solvent resistance, non-tackiness, electrical insulation, stain-proofing properties, and flame retardance, molded at a lower temperature than conventional fluororesins, and heat bonded or co-extruded with general-purpose resins having low heat resistance.
