The ductility/stiffness balance of a rubber-modified monovinylidene aromatic polymer, e.g., HIPS, is increased without increasing the rubber content of the polymer and/or changing the size of the average rubber particle by a process comprising the step of crosslinking the rubber such that the rubber-modified polymer has an optical crosslink index (OCLI) of < 0.5 and an injection molded/compression molded (IM/CM) modulus ratio ‰¥1.3. |
