Abstract
Flame-retarded transparent plastic compositions comprising polyhalgenated trimethylphenyl indan. The polyhalogenated trimethylphenyl indan is a mixture of polyhalogenated trimethylphenyl indanes having each 3 to 9 halogen atoms. The halogen may be bromine or a mixture of bromine and chlorine. The transparent plastic is selected from polycarbonate, polymethylmethacrylate, and polystyrene. The polyhalogenated trimethylphenyl indan is present in an amount of up to about 40% by weight. The transparent plastic flame-retarded material is prepared by mixing the plastic matrix with a flame-retardant effective amount of a polyhalogenated trimethylphenyl indan.
