Abstract: A catalytic composition for preparing a polyethylene terephthalate (PET) resin is provided. The catalytic composition comprises a polycondensation catalyst and cesium tungsten oxide (CsxWO3-yCly), and 0<x?1 and 0?y?0.5. A PET resin prepared by the catalytic composition above is also provided. The PET resin comprises 2-80 ppm of cesium tungsten oxide. This catalytic composition can solve the problems of slow solid-state polymerization rate of the PET preparation and thus the long preparation time, as well as yellowing. Moreover, the PET resin can absorb infrared radiation.

Abstract: The invention relates to a safety agglutination glass structure, comprising two glass substrates and a heat insulating adhesive membrane. The heat insulating adhesive membrane constituted of heat insulating particles and a colloid material is disposed between the two glass substrates. Therefore, the two glass substrates can combine together by heating and pressurizing for the purpose of simplifying processing procedures, reducing the costs and preventing distortion.
