Abstract
High impact resistant thermoplastic resins are produced in three steps: (a) graft polymerizing a minor amount of unsaturated monomer onto a major amount of diene type rubber polymer in latex form, (b) mixing the grafted diene type rubber latex with a monomer or monomers, extracting the grafted rubber polymer particles into the monomer phase and separating and discarding the water phase to obtain a grafted rubber polymer particle dispersed monomer solution, and (c) bulk polymerizing the resulting rubber polymer particle dispersed monomer solution.
