A polymer composition, a process for its preparation and a molded article formed from the polymer composition are claimed. The polymer composition comprises (a) a base polymer that is a poly(alkyl(meth)acrylate; and (b) a rubber toughening agent selected from the group consisting of (i) copolymers of (alkyl)acrylate rubbers, (ii) copolymers of vinyl aromatic monomers with (alkyl)acrylates, (iii) copolymers of vinyl aromatic monomers with conjugated diolefins; (iv) copolymers of vinyl aromatic monomers with monoethylenically unsaturated monomers, in which the rubber toughening agent is present in the polymer composition as discrete islands substantially surrounded by the base polymer and in which islands are sub-islands of the base polymer. |
