A thermoplastic composition includes from about 30 wt% to about 95 wt% poly(methyl methacrylate) (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%. A method of making a thermoplastic composition includes: (a) combining from about 30 wt% to about 95 wt% poly(methyl methacrylate) (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 mixture; and melt processing the mixture to polymerize it and form the thermoplastic composition. 一种热塑性组合物包括约30wt％至约95wt％聚(甲基丙烯酸甲酯)(PMMA)，和约5wt％至约70wt％的硅氧烷含量为约25wt％至约45wt％的聚(碳酸酯-硅氧烷)共聚物。一种制备热塑性组合物的方法包括：(a)将约30wt％至约95wt％聚(甲基丙烯酸甲酯)(PMMA)和约5wt％至约70wt％的硅氧烷含量为约25wt％至约45wt％的聚(碳酸酯-硅氧烷)共聚物组合，以形成混合物；和熔融加工所述混合物以使其聚合并且形成所述热塑性组合物。
