ABSTRACT:
The invention relates to an improved process for the mass polymerization of solutions comprising monoalkenyl aromatic monomers and optionally monoalkenyl nitrile monomers having a diene rubber dissolved therein wherein the improvement comprises dissolving a minor amount of an organic diperoxide compound in said solution and mass polymerizing said solution, said diperoxide initiating a higher molecular weight polymer fraction providing said polymer with a broader molecular weight distribution.
