A flame-retardant, optically clear thermoplastic molding composition is disclosed. The composition contains aromatic polycarbonate resin, a bromine-substituted carbonate oligomer, a phosphorous containing compound and an inorganic salt of perfluoroalkane sulfonic acid in amounts effective to impart to the composition flame resistance that in accordance with UL-94-5V standard is rated A at 3.00 mm and V-0 at 1.5 mm.

Flame retardant, optically clear thermoplastic molding composition

A molded article comprising (a) a rigid support, e.g., a rigid seat support ( ), having a plurality of perforations, and (b) a molded flexible hollow thermoplastic member ( ), e.g., a flexible thermoplastic seat cushion, fixedly attached thereto is described. A portion of the flexible hollow member (b) extends through at least some of the perforations of the rigid support (a), embedding the edges of the perforations therein. The flexible material extending through the perforations forms an attachment element, e.g., an attachment head, that serves to fixedly attach the flexible hollow member (b) to the rigid support (a). Also described is a method of preparing the molded article of the present invention, in which the flexible hollow member (b) is fixedly attached to the rigid support (a) during the blow molding formation of hollow member (b).
