Abstract: PROCESS FOR PREPARING IMPACT RESISTANT POLYVINYL AROMATICS of the disclosure There is disclosed an improved bulk-suspension process for polymerizing vinyl aromatic monomers in the presence of an ethylene-propylene-nonconjugated diene-rubber, which comprises using, in the suspension polymerization step, peroxy-carbonic esters as the polymerization initiator. The process of the invention yields products having improved notched impact strength, weatherability and elongation at break combined with a good shear stability.
