摘要： A process for producing a high impact polystyrene characterized by polymerizing a conjugated diene (preferably, 1,3-butadiene) by the use of an organolithium-based catalyst containing a polyfunctional organolithium compound (preferably, said organolithium-based cataylst is a mixture of a polyfunctional organolithium compound and a monofunctional organolithium compound at such a mixing ratio that the amount of lithium atom in the polyfunctional organolithium compound is 5% by weight or more based on the total sum of the lithium atoms in the respective compounds), coupling the resulting polymer molecules with a polyfunctional treating agent having at least two (preferably, 2-4 on the average) reactive sites capable of reacting with the active lithium terminal of the polymer, dissolving in styrene the conjugated diene polymer thus obtained, which has substantially a network structure and is substantially soluble in styrene, preferably in a proportion of 2-30% by weight, and then radical-polymerizing the resulting solution by bulk polymerization or bulk-suspension polymerization.
