Abstract: The instant disclosure relates to a polyester composition and method for preparing the same, as well as products comprising the polyester composition and applications thereof. The polyester composition comprises aliphatic polyester, titanium and zirconium, wherein the weight ratio of titanium/zirconium is greater than 0.05. The polyester composition of the present invention has a specific titanium/zirconium weight ratio range, can reduce the process time, and can obtain a biodegradable composition with a lower acid value.

Abstract: Laser weldable compositions are provided which in various examples include a tricyclodecane dimethanol-modified copolymer, a terephthalate-type polyester and an inorganic filler. Compared with compositions without the tricyclodecane dimethanol-modified copolymer, the compositions of the invention have improved, uniform laser transmittance, thereby welded products including the compositions have improved bonding strength and require stronger tensile strength to be torn apart.

Abstract: A quick positioning-charging device including a charging platform including power-terminal connectors which each includes probe terminals, an insulating body, and a female socket electrically connected to the power terminal. Accommodation frames are assembled on the charging platform, and each accommodation frame has an accommodation space for a mobile electronic device to be placed. A male plug of the male plug can be plugged with a charging hole of the mobile electronic device, to form electrical connection. The charging-terminal connector includes contact points for elastically abutting with probe terminals of the power-terminal connector to form electrical connection. The electrical connection structure of the mobile electronic device elastically abutted with the power-terminal connector of the charging platform can prevent the male plug connected to the power supply cable of the conventional charging device from being frequently plugged and pulled with a connector of the mobile electronic device.
