ABSTRACT:
Polycarbonate resins which contain sufficient halogenated phenolic residues to impart fire retardant characteristics to articles molded therefrom are stabilized by the addition of a hindered phenol selected from the group consisting of a high molecular weight hindered phenol phosphate, a high molecular weight hindered phenol cyanurate, an ester of a hindered phenolic carboxylic acid and an alcohol having 10-26 carbon atoms, and the reaction of a hindered phenol and an aldehyde. The polycarbonates with the stabilizers of the invention exhibit improved melt flow stabilities and hydrolytic aging characteristics over conventionally stabilized polycarbonates and in most cases over unstabilized polycarbonates.
