Abstract: Thermoplastic compositions include: from about 62 wt % to about 99 wt % poly(methyl methacrylate) (PMMA) or copolymers thereof; and from about 1 wt % to about 38 wt % of a poly(carbonate-siloxane) copolymer having a siloxane content of from about 25 wt % to about 45 wt %. The compositions are scratch resistant. Scratch resistance may be determined as comprising a scratch depth of less than 20 micron (μm) as measured in accordance with the Erichsen scratch hardness test at a force of 4 Newton (N). Articles including the thermoplastic composition are also described.
