Abstract: To provide an ethylene/tetrafluoroethylene copolymer excellent in the thermal resistance, and a method for its production. The ethylene/tetrafluoroethylene copolymer is produced by polymerizing ethylene with tetrafluoroethylene in an organic solvent containing no chlorine atoms as a polymerization medium, in the presence of a chain transfer agent containing no chlorine atoms and a polymerization initiator containing no chlorine atoms, and further in the substantial absence of a chain transferable compound having a carbon-chlorine atomic bond in the reaction system.

Abstract: A multilayer laminate containing a laminate (I)/(II) that is formed by directly bonding a layer (I) made of a fluororesin (A) having a functional group (a), said fluororesin (A) being an ethylene/tetrafluoroethylene/hexafluoropropylene/CH2?CH—Rf, wherein Rf copolymer is a C2-6 perfluoroalkyl group, and in the copolymer, the molar ratio of repeating units based on ethylene/repeating units based on tetrafluoroethylene/repeating units based on hexafluoropropylene/repeating units based on CH2? CH—Rf ranges from 40/47/10/3 to 46.9/46.9/6/0.2 and a layer (II) made of a thermoplastic resin (B) having a functional group (b) that is capable of forming a chemical bond by reacting with the functional group (a) of the fluororesin, wherein the fluororesin (A) has a melting point ranging from 120 to 230° C.

Abstract: A multilayer laminate containing a laminate (I)/(II) formed by directly bonding by means of thermal lamination or the like, a layer (I) made of a fluororesin (A) with a functional group (a) and a layer (II) made of a thermoplastic resin (B) with a functional group (b) capable of forming a chemical bond by reacting with the functional group (a) of the fluororesin, wherein the fluororesin (A) has a low melting point of from 120 to 230° C. The laminate may, for example, be a multiplayer laminate containing a layer obtained by directly laminating a layer (I) made of a fluororesin (A) containing an acid anhydride residue (for example, a tetrafluoroethylene/ethylene/hexafluoropropylene/(perfluorobutyl)ethylene)/itaconic anhydride copolymer) and a layer (II) made of an amine-modified thermoplastic resin (B) (for example, a polyurethane modified with a silane coupling agent containing an amino group). The laminate is excellent in interlayer adhesion and productivity.

Abstract: A data processing system for storing and managing at least one shared document in a storage unit, includes a memory unit for storing first information that indicates update levels comparable to frequencies of access to shared documents in one-to-one correspondence with users, and a control unit for controlling access to the memory and storage and management of the shared documents. The control unit includes a unit that when a first user accesses any of the shared documents so as to update it, retrieves a latest update level of the shared document accessed from the first information and determines on the basis of the result of retrieval whether there is a second user who has accessed the shared document before the first user, and a unit that when the result of determination reveals that there is a second user, notifies the second user of the fact that the shared document has been updated by the first user.
