Disclosed are rubber-modified monovinylidene aromatic polymers with improved toughness and rigidity as well as a process for the preparation thereof. The polymer comprisesa) a monovinylidene aromatic polymer matrix; andb) rubber particles dispersed therein, characterized in that the rubber particles are produced from a diene rubber having substantially linear structure containing less than one long chain branch per 10,000 carbon atoms in the polymer backbone with a solution viscosity of 5 cPoise to 1000 cPoise and a Mooney Viscosity of 5 to 120.
