Zusammenfassung:	PURPOSE:To uniformize the particle diameter of a copolymer bead by formulating a specific quantity of a specific solfonate unit, a specific acrylate unit, etc., and an alkylacrylate nit and preparing a suspension polymerization dispersant. CONSTITUTION:A 100-40wt.% monomer unit indicated by a formula 1 [wherein a substituted position to a phenyl group of SO3M represents one of (o), (m) and (p), R represents H and CH3, and M represents Li, Na, K and NH4 respectively], a 0-60wt.% one or more of the acrylate unit and/or a methacrylate unit of an Li, Na, K and ammonium salt of acrylic acid and/or methacrylic acid, and a 0-50wt.% an alkylacrylate and/or an alkylmethacrylate having an alkyl group of 1-8 carbon atoms. are formulated to manufacture the suspension polymerization dispersant.
