Poly(methyl methacrylate) is modified to have improved impact resistance by forming an ABA-type block copolymer where the A segments are poly(methyl methacrylate) and the B segment is polycarbonate. The ABA block copolymer is moldable, transparent and has a number average molecular weight (Mn) in the range of from about 15,000 to 100,000.
