摘要:
The present invention aims to provide a surface-treated phosphor having high dispersibility and capable of significantly enhancing moisture resistance without deteriorating the fluorescence properties, and a method for producing the surface-treated phosphor. The surface-treated phosphor includes: a phosphor body; and a surface treatment layer containing at least one specific element selected from elements of the third to sixth groups of the periodic table, and fluorine, the phosphor body having the surface treatment layer on the surface thereof, wherein, when a cross section of the surface treatment layer is subjected to a thickness-wise elemental distribution analysis by a combination of an electron microscopic analysis and an energy-dispersive X-ray element analysis, a peak indicating the maximum content of the specific element appears nearer to the surface than a peak indicating the maximum fluorine content.

摘要:
The present invention provides a process for producing a polyester ether copolymer which comprises conducting polycondensation after or while melting and mixing a polyester, of 0.3 (dl/g) or more in intrinsic viscosity, and a polyether having hydroxy groups or their derivatives at its terminals and having a molecular weight of 200 or more. The present invention can dispense with the steps of esterification, transesterification, etc., because of the use of the preformed polyester. Moreover, it shortens the reaction time so that only a small quantity of polyester is produced as a by-product. In addition, since the thermal history of the polyesterh is so small, deterioration of the polymer during production is suppressed. Furthermore, this process enables continuous production of products with good quality, which serves to markedly improve productivity.
