摘要： PROBLEM TO BE SOLVED: To obtain the subject resin improving the gloss of the formed product thereof, also maintaining excellent characteristics in a good balance and having a new function by imparting a specific condition in a continuous bulk polymerization and/or a continuous solution polymerization. SOLUTION: This method for producing an ABS-based polymer is constituted by containing a process that a polymer of (A) a monomer component forms a continuous phase and particles of (B) a rubbery polymer forms a dispersion phase, which process in turn contains a particle forming sub-process of the component (B) as a first stage process and a particle size adjusting sub-process as a second stage process in a continuous bulk and/or continuous solution polymerization method. Also the first stage process is performed in a polymerization system using a plug flow type reaction vessel or in a batch polymerization vessel, at least until when the particles of the component (B) are formed in the polymerization mixture, and the second stage process is performed by increasing the amount of the conversion of the component (A) to the polymer compared with that in the first stage, and also reducing the size of the particles of the component (B) formed in the first stage process. Further, in the presence of 4-50 pt.wt. component (B), 100 pts.wt. monomer component consisting of a styrene-based monomer, an acrylonitrile-based monomer and a vinyl monomer copolymerizable with the monomers are used as the as component (A).
