Abstract:
Thermoplastic compositions include: (a) from about 30 wt % to about 95 wt % poly(methyl methacrylate) (PMMA); and (b) from about 5 wt % to about 70 wt % of a poly(carbonate-siloxane) copolymer having a siloxane content of from about 25 wt % to about 45 wt %. Methods for making a molded article, include: (a) combining from about 30 wt % to about 95 wt % PMMA and from about 5 wt % to about 70 wt % of a poly(carbonate-siloxane) copolymer having a siloxane content of from about 25 wt % to about 45 wt % to form a blend; (b) melt processing and pelletizing the blend; and (c) injection molding the article from the melt processed and pelletized blend.
