Abstract: A polycarbonate composition includes: a continuous polycarbonate phase; discontinuous first domains distributed in the continuous phase, and comprising a core-shell silicone-(meth)acrylate impact modifier comprising a silicone elastomer core and a (meth)acrylate copolymer shell, wherein the first domains have an aspect ratio of at least 1.7, preferably at least 1.8; and discontinuous second domains distributed in the continuous phase, and comprising an alkenyl aromatic-olefin block copolymer impact modifier, wherein the second domains have an aspect ratio of at least 3, preferably at least 4, and a domain size of 6400 square nanometers or less, more preferably 5700 square nanometers or less. Optionally, the polycarbonate composition includes: a polycarbonate; a brominated polycarbonate different from the polycarbonate; a poly(carbonate-siloxane) comprising 30 to 70 weight percent of siloxane blocks; a core-shell silicone-(meth)acrylate impact modifier comprising a silicone elastomer core and an (meth)acrylate copolymer shell; and an alkenyl aromatic-olefin block copolymer impact modifier.

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.

Abstract: A thermoplastic composition includes: from about 5 wt % to about 70 wt % poly(methyl methacrylate) (PMMA); from about 15 wt % to about 50 wt % of a first poly(carbonate-siloxane) copolymer having a siloxane content of from about 35 wt % to about 45 wt %; and from about 10 wt % to about 45 wt % of a second poly(carbonate-siloxane) copolymer. The second poly(carbonate-siloxane) copolymer has a siloxane content of from about 15 wt % to about 25 wt % or from about 4 wt % to about 8 wt %.
