Abstract: The present invention is directed to a composition comprising: (a) a polyethylene terephthalate; (b) a copolycarbonate of 2-phenyl-3,3-bis(4-hydroxyphenyl)phthalimidine (PPPBP) and another bisphenol; (c) a polycarbonate-polysiloxane copolymer; and (d) a non-halogenated flame retardant. The invention is also directed to processes for making such compositions as well as articles derived therefrom.

Abstract: A laser weldable composition made from a process of melt blending a combination of a partially crystalline thermoplastic polyester component such as poly(butylene terephthalate), an amorphous thermoplastic polycarbonate having a Fries rearrangement of greater than 150 to 10,000 ppm, and a filler such as glass fiber. The laser weldable composition has a polycarbonate aryl hydroxy end-group content of at least 300 ppm and provides improved near infrared transmission at 960 nanometers. A method welding components made from the weldable composition and welded articles made therefrom are also disclosed.

Abstract: The present invention deals with a thermoplastic composition comprising (a) a compatibilized polyphenylene ether-polyamide base resin, and (b) 1-7 parts by weight per 100 parts by weight of (a) of an electroconductive carbon black, with an Izod notched impact strength of more than 15 kJ/m.sup.2 and a volume resistivity of less than 10.sup.6 Ohm.cm.The compositions of the invention are suitable for molding objects which can easily be painted by an electrostatic coating process.The invention further provides a process for the preparation of the composition of the invention comprising at least two steps. In the first step the base resin is formed. In a further step the carbon black is incorporated in the base resin.The invention further relates to articles formed out of the composition of the invention and to such articles which have been painted by an electrostatic coating process.
