| abstract |
The present invention relates to a suspension polymerization method of a methacrylic resin using an alkali-soluble polymer emulsion as a dispersion stabilizer, and the method is excellent for polymerization stability, reduces the amount of scale produced in a reactor and suppresses the production of fine particles as much as possible, thereby enabling yield and productivity. In addition, the present invention provides a suspension polymerization method which is economical and convenient since all the alkali-soluble emulsion polymers used as a dispersion stabilizer are collected from an aqueous medium, thereby facilitating reuse of the used solvent. |
