摘要： A method is provided for continuously manufacturing high impact strength thermoplastic resins comprised of the sequential steps of (a) bulk-polymerizing a monomer solution, which contains a diene type rubber polymer or a graft polymer obtained by extracting the rubber polymer particle or vinyl monomer grafted polymer particle in latex with vinyl monomers which contain 5-20 percent by weight of water at a temperature of 85.degree.-135.degree.C, while continuously stirring the solution, vaporizing the volatile components, condensing the volatile component and recycling them back to reaction mixture, until the solid content in the reaction mixture reaches 40-75 percent by weight, and thereafter (b) bulk polymerizing the resulting prepolymer solution under the condition that plug-flowing can be attained with a temperature gradient 100.degree.-170.degree.C at the top of the reaction vessel and 170.degree.-270.degree.C at the bottom thereof, while the volatile component of the mixture are evaporated off, condensed and recycled to the reaction mixture, until the solid content is at least 90 percent by weight.
