Notch width sensitivity, a serious deficiency of polycarbonate, can be improved by addition of 3–10 percent of specially modified methacrylate‐butadiene‐styrene (MBS) graft polymers. Blends of these modifiers with polycarbonate are transparent, in contrast to polycarbonate blends with previously reported notch width sensitivity improvers which are opaque. The synthesis of these modifiers is described together with physical properties of polycarbonate/modifier blends.
