Thermally stable polymers, method of preparation, and articles made therefrom
The present invention provides compositions comprising (a) a thermally stable polymer comprising resorcinol arylate polyester chain members substantially free of anhydride linkages linking at least two mers of the polymer chain, and (b) at least one auxiliary stabilizer additive selected from the group consisting of 2,2&#8242;-(1,4-phenylene)bis(4H-3,1-benzoxazin-4-one) and 1,3-bis[(2-cyano-3,3-diphenylacryloyl)oxy]-2,2-bis[[(2-cyano-3,3-diphenylacryloyl)oxy]methyl]propane. Both multilayer and unitary articles comprising the composition are also provided.
