In a process for preparing rubber modified high impact resins (HI-PS and ABS) by polymerizing a starting monomer containing an aromatic vinyl monomer or a mixture of an aromatic vinyl monomer and a vinyl cyanide monomer and added with a rubber-like polymer and by using at least two polymerization reactors and a particle disperser placed between the both reactor, the process obtaining the resins of high grade by specifying the relationships between the concentration of the polymerized monomer in the first reactor and the content of the rubber-like polymer in the first reactor and between the volume occupied by the polyemrizing liquid in the first reactor and the inner volume of the particle disperser, and the peripheral linear velocity of a shearing stirrer in the particle disperser.
