Abstract: A food container and a refrigerator including the same are disclosed. The present invention relates to a food container capable of simultaneously separating fixing members (50, 60, 70) of a cover according to sliding of a handle and of taking out of food kept therein by opening an auxiliary cover (90) even in a state of a main cover being closed, only to be usable conveniently, and a refrigerator including the food container.

Abstract: The present invention relates to polyarylene sulfide, in which a ratio of a peak area of a polymer chain of a second polyarylene sulfide having a lower molecular weight than the maximum peak molecular weight to a peak area of a polymer chain of a first polyarylene sulfide having a higher molecular weight than the maximum peak molecular weight is 1.3 or less in the molecular weight distribution of the polyarylene sulfide, as measured by gel permeation chromatography using polystyrene as a standard, and a preparation method thereof. This polyarylene sulfide exhibits excellent processability and generates no burrs (flashes) or the like, and can satisfactorily mold a product requiring high molding precision.

Abstract: Disclosed is a method for preparing a polyester resin, wherein phosphate additives are used in preparing polyester resin to improve the reactive property of the esterification reaction or transesterification, as well as the flame retardancy property and the color stability of a polyester resin. The method for preparing a polyester resin comprises the steps of: esterification reacting and/or transesterifying diacid ingredients diol ingredients in the presence of one or more phosphate additives selected from the group consisting of the compounds as defined in Chemicals in the detailed description of the invention; and polycondensing the products obtained from the esterification reaction and/or transesterification.

Abstract: The present invention relates to a method for preparing a polyester resin in which isosorbide is copolymerized, and more particularly, to a method for preparing a copolymerized polyester resin containing isosorbide, comprising the steps of: adding glycols containing ethylene glycol and isosorbide to terephthalic acid or dimethyl terephthalate such that the feed molar ratio of total glycols to terephthalic acid or dimethyl terephthalate is 1.05 to 3.0 to allow an esterification reaction; and polycondensing the esterification product using titanium-based compounds of copolymers of titanium dioxide and silicon dioxide, and copolymers of titanium dioxide and zirconium dioxide, as a copolymerization catalyst, and using phosphorous compounds as a stabilizer. The copolymerized polyester resin containing isosorbide prepared according to the present invention exhibits superior reactive properties and productivity, and reduces the quantity of metal used as a catalyst and improves the clarity of a polymer.
