Claims6
A flame retardant, impact resistant aromatic carbonate polymer composition consisting essentially of a mixture of (a) one or more carbonate polymers, (b) an impact modifying quantity of a rubbery polymer selected from the group consisting of styrene/methylmethacrylate copolymers grafted onto homopolymers or interpolymers of butadiene, and (c) from 0.01 to 10 percent by weight of the total composition of a fluorine containing polymer of the fibril forming type.
A composition according to claim 9, wherein the carbonate polymer is a polycarbonate of bisphenol A.
