摘要： The invention relates to a process for producing 1,1,1-trifluoroacetone, which is useful as an intermediate of pharmaceuticals and agricultural chemicals, or as a reagent for introducing fluorine-containing groups. This process includes the step of conducting a hydrogenolysis of a halogenated trifluoroacetone, which is represented by the formula [1], by a hydrogen gas, in a liquid phase containing water, in the presence of a catalyst containing a transition metal, where X represents a chlorine, bromine or iodine, and n represents an integer from 1 to 3. It is possible by the process to easily produce 1,1,1-trifluoroacetone with high purity.

摘要： The invention provides a fluorine-containing resin blend. This resin blend includes 100 parts by weight of a first resin and 1-50 parts by weight of a second resin. The first resin is one of an elastic fluorohydrocarbon resin and a vinylidene fluoride based resin. The second resin is a graft copolymer prepared by graft copolymerization of a rubber-like polymer with a first monomer and an optional second monomer. The first monomer is at least one of an acrylic ester and a methacrylic acid ester. The optional second monomer is at least one copolymerizable monomer other than the first monomer. When the elastic fluorohydrocarbon resin is used as the first resin, the resin blend is improved in extensibility upon molding in a melted condition and lowered in modulus of elasticity under a condition that the resin blend is strained by up to 20%, without impairing the elastic fluorohydrocarbon in its heat resistance, low-temperature characteristics and the like. When the vinylidene fluoride based resin is used as the first resin, the resin blend is improved in mechanical strength at low temperature, without impairing superior characteristics of the vinylidene fluoride based resin.

摘要： A plastic laminate having an apliphatic polyamide resin surface layer and a fluororesin surface layer is produced by using an intermediate layer formed of a blend of an aliphatic polyamide resin with a fluorine-containing graft copolymer, which is obtained by graft polymerization of a suitable monomer such as vinylidene fluoride, or a mixture of monomers, with an elastomeric copolymer of at least two principal monomers including at least one fluorine-containing monomer, e.g. vinyliden fluoride and chlorotrifluoroethylene, and an unsaturated peroxy compound. The fluorine-containing graft copolymer is a soft, flexible resin and is well compatible with aliphatic polyamide resins and also with various fluororesins. The fluororesin surface layer uses, for example, polyvinylidene fluoride, a vinyliden fluoride based copolymer or the fluorine-containing graft copolymer. The lamination can be accomplished by simply welding the two surface layers to the intermediate layer. The laminate can be produced in tubular form by a coextrusion method and can be used, for example, as an automotive fuel hose.
