High‐impact polystyrene is prepared in a novel one‐step method in which the starting elastomer is present as a latex but the finished resin is recovered as suspension beads. The reaction is initiated by either oil‐soluble or water‐soluble catalysts. Evidence is presented to show that polymerization begins when the system is still in the latex phase, even when an oil‐soluble suspension catalyst is used exclusively.
