Abstract

PURPOSE: To obtain an impact-resistant resin free of formation of coarse particles and prevented from becoming glutinous by adding orderly a suspension stabilizer and a coagulant to a latex obtained by grafting an ethylenic monomer into a rubbery polymer by an emulsion polymerization, followed by a suspension polymerization.
CONSTITUTION: A grafted coplymer latex, obtained from the emulsion polymerization of a rubbery polymer, e.g., butadiene rubber, and an ethylenic monomer, e.g., styrene, acrylonitrile, etc., is mixed with a suspension stabilizer (i), e.g., MgCO3, a sulfonated polystyrene, etc., and then with a coagulant (ii) selected from acidic substances or electrolytes, e.g., sulfuric acid (or Mg salt), etc., to cause a partial coagulation to take place, and then remaining ethylenic monomer is added to the reaction system to form an aqueous low-viscous and stable dispersion which is, in turn, subjected to a suspension polymerization to obtain the objective resin.
EFFECT: A resin which is excellent in thermal stability and surface gloss upon hot molding can be obtained.
