The present invention relates to a copolymer for suspension dispersant of suspension polymerization having excellent polymerization stability and a suspension polymerization method of a vinyl-based resin using the same, including 10 to 85 wt% of the monomer of Formula 1, 5 to 45 wt% of the monomer of Formula 2, and ( It is a copolymer obtained by homogeneously polymerizing a monomer mixture composed of meta-acrylic acid ester monomers in an aqueous solution of 10 to 45 wt%. Provided are a dispersant for coalescence and a method for preparing the same. [Formula 1] (Wherein R 1 is H or CH 3 and M 1 is any one selected from lithium, sodium, potassium and ammonium salts.) (2) (Wherein, R 2 is H or CH 3 , M 2 is any one selected from lithium, sodium, potassium, ammonium salt.) |
