FLAME RETARDANT, OPTICALLY CLEAR THERMOPLASTIC MOLDING COMPOSITION

摘要

The present invention relates to a flame-retardant, optically clear thermoplastic molding composition. The composition contains a A) about 60 pbw to about 97 pbw of a polycarbonate, B) about 1 pbw to about 20 pbw of bromine- substituted oligocarbonate, C) about 1 pbw to about 20 pbw of a phosphorus- containing compound and D) about 0.01 pbw to about 1 pbw of at least one alkali or alkaline- earth salt of perfluoroalkane sulfonic acid and optionally E) about 0.01 to about 1 pbw of a phosphite antioxidant/stabilizer. In accordance with UL-94 standard the flame-retardant, optically clear thermoplastic molding composition is rated 5VA at 3.00 mm and V-O at 2.3 mm, more preferably V-O at 1.5 mm according to UL-94.
